My Singing Monsters Wiki

Unlike the common Wubbox, the Rare can be bought for a song - as long as you're singing the right tune. In this inactive state, it's hard to tell what physically differentiates the two monsters, but the most striking contrast is the Rare Wubbox's modest bed count - it's only one! We're hoping to learn more once this cryptic creature is powered up with monsters and awakens to share its song.

In-game description of inactive Rare Wubbox
The story goes that this monster yearned to learn more about the human world, and embarked on a journey through the multiverse. It's now obvious that the Wubbox hurtled not only through space, but also time, towards its destination. Upon its return, it extolled the virtues of revolutionary music tech like turntables, keytars and vocoders. Thanks to its talent for self-customization, the Wubbox integrated pieces of its discoveries into its very being, forever altering its shape, song, and completing its transformation into the sensational Rare Wubbox.
In-game description of active Rare Wubbox
Well, well, well… looks like it's time to officialize the previously speculative monster class of 'Superethereal' - now it has two members! Just like its Supernatural cousins, this Electric Elemental isn't just a Monster World traveler, but a dimension traveler as well, having made stops in the human world before finally settling in the pocket dimension. Despite the Rare Wubbox's distinct appearance, all Wubbox exteriors have the same versatile chemical composition that allows for Monsters of various elements to be 'boxed' inside. It's believed that this unique material shared many properties with Bubblerite, a mineral native to the Monster World with creative potential housed inside every molecule.

In-game description of inactive Rare Wubbox on Ethereal Island

It was a long time coming but Rare Wubbox has finally joined the chorus of Ethereal Island, complete with its unique musical offerings synthesized from computer error messages it overheard during its travels in the human world! The increased presence of the Wubbox and its variant subspecies strengthens the theory postulated by some that the pocket dimension served as a sort of experimental sandbox for ancient beings endowed with the spirit of creation, before formalizing their handiwork in the main dimension. Obviously, we are not finished learning about the mysterious early days of the Monster World. Rare Wubbox seems to gravitate towards a particular meadow on Ethereal Island, where the fabric of reality has frayed and allowed pieces of different dimensions of the multiverse to cross over.
In-game description of active Rare Wubbox on Ethereal Island


The Rare Wubbox is activated in a similar manner to the regular Wubbox. The major difference is that instead of needing to box one of each natural monster on the islands in which it resides, be it Plant Island, Cold Island, Air Island, Water Island, Earth Island and Gold Island, it requires natural Rare Monsters instead. On Ethereal Island it requires Rarethereal monsters.

Just like the regular variety, the Rare Wubbox boxing requirement can be bypassed by using diamonds. It costs 38 Diamond25px.png for each monster to be filled and will cost 570 Diamond25px.png in total if the feeding process is bypassed completely. (18000 on ethereal island due to the rarity of Rarethereals). Once one of each Rare Monster is given to the Rare Wubbox, it will activate and be able to generate coins, be able to be fed to increase its level, up to 20, and also have its own unique set of likes of certain monsters and decorations.

Boxing Monsters

Boxing is done using the exact same process for the Rare Wubbox as one would for the regular Wubbox. The sole difference is that the monsters that must be Boxed may only be of the Natural (Rare) class. A "Box It" option will always appear in all monster menus, regardless of whether or not they are allowed to be boxed, or still needed for boxing. At any rate, a monster cannot be boxed if they are not needed. The game blocks that action and displays a notification before completing the Boxing. Once the Rare Wubbox is placed on an island, and once another placed monster is selected, an additional option to "Box It" appears. Additionally, the option to "Box it" shows up in the Nursery after the Rare Wubbox is placed. Thus, monsters can go straight from the nursery into the Rare Wubbox without being placed on the island first.

After a monster has been boxed, it doesn't count towards the happiness of other monsters, even with the effects of a Unity Tree. For example, suppose there is a Ghazt on Plant Island that's at 100% Happiness, in part because there is also a Rare Entbrat there as well. But if that Rare Entbrat is boxed, the Ghazt's Happiness will reduce to 75%, assuming there is no common Entbrat on the island. Another common Entbrat or Rare Entbrat would need to be placed in order to restore the Happiness of the Ghazt.

Technically, once a monster has been Boxed, it is "gone." It doesn't generate coins, and it doesn't make other monsters happy. If the Boxed monster was at Level 15 and had appeared on Gold Island, Boxing it on its natural island will also make it disappear from Gold Island, for example if you had a Mammott on Gold Island and from its natural island, and teleported it to Shugabush island, it is removed from Gold Island.

Activation on Gold Island

Like its common counterpart, the Rare Wubbox can be placed on Gold Island at Level 15+, but it will be initially inactive. To activate it, one must box one of every level 15 Rare Monster. Boxing these monsters on Gold Island will remove them from their home island. If a Rare Wubbox is removed from Gold Island, it will go back to its inactive form again. As for the other islands, this activation may be sped up using diamonds, though each Rare monster missing costs 375 Diamond25px.png, for a grand total of 11,250 Diamond25px.png for a fresh Rare Wubbox.

This activation counts for "Power up a Wubbox on Gold Island" goal, however, packing rare monsters does not count for "Box all NNN (natural) Island monster species in a Wubbox on Gold Island" goals.

Activation on Ethereal Island

On Ethereal Island, the process is essentially the same as all natural islands, except all Rarethereal monsters must be used.

As for the other islands, you may use diamonds to speed this up, although each monster costs 1200 diamonds for a whopping 18000 diamond total cost.


The Rare Wubbox is a monster that had been released in December 10th 2015. It had first been released on the Version 1.3.7 update, exclusively at Plant Island. It had been included in Cold Island since 22nd July 2016, 19:00 UTC, during Version 1.4.3. It had been included in Air Island since 23rd September during the 2.0.0 update, at approximately 18:00 UTC. It had been released to Water Island and Earth Island unofficially on 23rd December 2016 and became fully released on 4th January 2017, at approximately 19:00 UTC.

Rare Wubbox record close-up

The Rare Wubbox is very different from its regular counterpart. It has keyboard keys on its arms, it has a grille-like mouth, the core in the middle is replaced with a vinyl record, and has green eyes rather than red, as well as yellow electricity instead of blue. The record's label, when examined closely, reads "skinny puppy". It isn't possible to read the album title.

The Rare Wubbox in box form is similar to a Common Wubbox, with some differences. Instead of being yellow and brown, the box is colored salmon and silver. The button on top is replaced by a vinyl record and player, and there are several speakers on it. The doorway now lacks stairs and rocks, and appears to have a car grille over it. The two pillars also have small keyboards.

Powered up, the Rare Wubbox has the same color scheme as the box, green eyes and blue eyelids (as opposed to maroon and red), a huge mouth that moves as of version 3.3.1 during its idle animation following a similar pattern to Common Wubbox but glitchier, and its parts are connected by yellow electricity. The monster's feet also lack the common toes, being one whole pad. Occasionally, when the Rare Wubbox expands its arms, there appears to be the sort of bars one would see on a media player (which has red, orange, yellow, and green bars, which represent the volume) on the extended part of its arms. It appears to be missing its right shoulder pad, sporting an arched metal piece instead.

Rare Wubbox in Earth island.

Unlike other Rares, who have songs identical to their counterpart, this Wubbox's sound is a medley of synthesized garbling and vocalized words, with a voice similar to that of someone speaking through a talkbox on keyboard or a vocoder. Its voice is so distorted that it's hard to make out what it is saying. The exception for this was when the monster is on Gold Island; it may less distorted.

It uses technical words such as "error", "loading", "volume" and "overflow", like when a computer receives an error or when the loading bar is low, medium or high. For a discussion and various interpretations of its exact phrases and lyrics, see the talk page. Many myths were spread of monsters being trapped against their will and want out, as the community believed, after a YouTube video was created by tgc20051 explaining that the monsters want out. Words on Plant Island were believed to be Let us out, let us out!, and lyrics on Cold Island were believed to be Fearful we won't sing, We're fearful we won't sing!, which was later debunked by the Monster-Handlers. (See next paragraph)

When asked about the exact lyrics, the Monster Handlers initially declined to comment. However, during the My Singing Monsters Live episode 88 the Monster-handler managing the chat explained that they were all computer error messages

See also the Wikipedia articles on Mondegreen, apophenia, and pareidolia.

For the Anniversary Celebration 2021 trailer, the lyrics for Rare Wubbox were confirmed.

  • On Plant, it says “Wubbabunga! -stuttering- Path not found, path not found.”
  • On Cold Island, it says “Buffer overflow! (Repeated)”
  • On Air Island, it says “Wubadubadup, failing! Error. -stuttering- Buffer overflow!”
  • On Water Island, it says "Wubtastic. x3 Error.”
  • On Earth Island, it says “Wub up the volume, wub up the volume, -stuttering- wub up the volume! Bad request. -stuttering- Bad request. Error, -stuttering- Error! -stuttering- Error! Bad request. -stuttering- Bad request."
  • On Gold Island, it says “Error -stuttering- E-e-e-e-File not found. W-w-w-Wubbox failed to launch. Loading, loading!”
  • On Ethereal Island, it says “File.. Not.. Found… -stuttering- File.. N-n-not.. Found.. -stuttering- Found."


Just like its regular counterpart, the Rare Wubbox cannot be bred; it can only be purchased in the StarShop, not the regular Market. Fortunately, it is available at any time of the year. Currently, it can only be bought on Plant, Cold, Air, Water, Earth, and Ethereal Islands, for 1 Starpower, almost free.

Once it has been activated and fed to at least level 15, it can then be teleported to Gold Island, unless its home is Ethereal Island.

Earning Rate and Maximum Income

Earning rate is in Coins per minute or Shards per hour and depends on Happiness % (Likes increase Happiness), also each monster has a limit to how much income it can hold at a time. Increasing the monster's level increases the limit. Earning rate is for an Activated Rare Wubbox only (until fully "fed" it produces nothing except rest notes).

Every monster has different things that they like. For every unique object that they like that's placed near the monster, the monster's happiness will increase by 25%. Placing more than one of the same liked item near a monster will still only increase its happiness by 25%. If there's a Unity Tree on the island, items don't need to be near the monsters. Below are the things liked by Rare Wubbox:

Buying a Filled Rare Wubbox

If all Rares are available to Buy for Starpower (Starpower), which sometimes happen during Seasonal or Anniversary events, then you can buy and fill a Wubbox instantly. There are different strategies using the resources differently.

Monsters should not be bought from the Market with Diamonds but instead using the button to buy all remaining.

Speedups cost is calculated assuming an Enhanced Nursery. Upgrading the Nursery (25 Diamonds) is usually worth it if speeding up many Monster eggs in Nursery.

Ethereal island

Rarethereals cannot be bought for Starpower, which negates this strategy. It costs 18000 diamonds and 1 Starpower to fully power it up.

Selling a Rare Wubbox

An empty Rare Wubbox is worth 0 Coins Coins. This makes it not at all a useful strategy to gain Coins by spending 1 Starpower. The selling price will always only be worth approximately the total selling cost of each of the Monsters within if they had been sold separately. Rare Wubbox was the only Rare Monster to have a different selling price from its Common version prior to version 3.3.0 that released at the start of Anniversary Month 2021, which changed the sell prices of basically every monster in the game.

The selling price of a full and activated Rare Wubbox thus depends on the Island it is on:

Island Selling price Contained Monsters' worth

On all islands, Rare Wubbox sells for the total of the Monsters within; since Rare Drumpler's price is less than the other Rares, Cold and Water Island Rare Wubbox sell for 25,750 Coins more.

Possible Monster Names

To see all possible names for Rare Wubbox, see Monster Names.


  • Using diamonds to fill the rest of the Rare Wubbox's inventory can sometimes be a better, less time-consuming option, as all Rare Monsters are only available through certain special events that may take tons of weeks/months to successfully collect/breed. Buying them all at once allows you to gain these Rare Monsters when they're not currently in event.
    • In the Collection of Monsters, if you attempt to look at a Rare monster that you haven't found it yet when it's not currently in event, that monster would be unavailable until you fill up a Rare Wubbox at once.
  • The reason why the Rare Wubbox was kept at September 1, 2016 is because of its low cost of Starpower and different animation and singing.
  • It is recommended to get a Rare Wubbox first due to its lowest cost and high coin income before you get a common Wubbox which costs 75 million coins, wasting so many coins.
  • The Rare Wubbox was teased here on this Facebook link.
  • During its activation animation, the Rare Wubbox yells "Error!" in a distorted way.
  • The Rare Wubbox is at current the most efficient monster in terms of coin production. The cost of this monster was at 1 Starpower. At level 1, it only requires one bed and in return gives a whopping 54,000 coin maximum income, compared to the 43,200 maximum income and 15 minimum coin production rate gained from the common Wubbox (which requires 6 beds).
  • The Rare Wubbox is also the only Rare to have a different song than its common counterpart even though its egg is affected by a shimmer.
  • Even though its egg is affected by a shimmer which is similar to other Rare monsters, it is not really a rare and that shimmer is all-year round when you reach level 20.
  • Before the addition of the Epic Monsters, the Rare Wubbox was the only monster to like decorations from the StarShop.
  • Its idle animation is different on Ethereal island, making it the only monster to have a different idle animation on a different island.
  • Prior to Version 3.3.1, it would not move its eyes or mouth.
    • This was changed in Version 3.3.1, and Rare Wubbox now moves its eyes and mouth like its common & epic cousins.
  • The Rare Wubbox costs the the least amount of Starpower in the StarShop, requiring only 1 Starpower, but it sells for 0 coins when inactive.
  • The Rare Wubbox has the longest incubation time of all monsters at 60 hours, beating Rare Dragong and Rare Fung Pray at 53 hours, and the other double-element Rarethereals at 52.5 hours.
  • Rare Wubbox was released to Cold island on July 22, 2016. At the same day it was first released to Cold Island, all natural Rares of Cold Island were discounted by half. This did not occur with the initial release at Plant Island though.
  • Rare Wubbox is the first non-natural monster to speak English, followed by Brump and Blipsqueak.
  • In the Original Soundtrack, the Rare Wubbox could be heard on Water and Earth island before its official release there. This is also the case for several monsters, such as the Wubbox in the Wublin Island soundtrack.
  • It is possible to have an inactive common Wubbox and Rare Wubbox at the same time. This does not conflict each other as they do not require the same monsters - the common Wubbox requires common Natural Monsters while the Rare Wubbox requires Natural Rare Monsters.
  • The Rare Wubbox has the same powering up sound as for the common counterpart.
  • On Gold Island, boxing every Rare Monster using only Starpower and Food in requires Starpower70,000 (35,000 for discount) and Treats8,192,000 (this is not counting food for the Rare Wubbox).
  • For a period in December starting Friday the 23rd, the Rare Wubbox was on sale on all Islands in the Market for free. It also was in the market of the Water and Earth Islands, despite the fact that it hadn’t been released on these islands yet. The Water and Earth ones were missing animations and used the song of the common Wubbox on the islands. From this, it can be inferred that the Rare Wubbox's addition to the Market during the sale was accidental.
    • On January 3rd 2017, Rare Wubbox was added to the StarShop on Water Island and Earth Island. Rare Wubbox was also fixed for people who had the Rare Wubbox before it was officially added to the StarShop, which was unofficially released on December 23rd 2016.
  • On Water Island and Earth Island, the disc on the Rare Wubbox's chest does not ever move when it sings its song. On Ethereal Island, the disc moves periodically.
  • Rare Wubbox on Water Island and Earth Island got released at the same time, despite it being released on one island at time before. Its icon was also leaked in the book of monsters before released.
  • There appears to be writing on its record. Part of it appears to be the My Singing Monsters logo, but it actually says Skinny Puppy which was a Canadian industrial music group.
  • Rare Wubbox also doesn't appear on Wublin Island, unlike its common counterpart.
  • Rare Wubbox's codename is O, which the game thinks is the Legendary element, compared to the Shugafam and the Werdos. This is likely a mistake, because Rare Wubbox is not supposed to be Legendary. It's Z for the Shugafam and VOC for the Werdos.
  • Originally, there was a bug that allowed you to have more than one Rare Wubbox per island. Now it works since 2.0.0. It is possible to do this, because of the monster not requiring the same monsters, as monsters can't switch between islands. For example, a Rare Mammott on Plant Island can't be switched to Cold Island.
  • Rare Wubbox is the only Rare monster to have a different number of beds.
  • Unlike its Common version, Rare Wubbox up the same amount of beds on Ethereal Island as it does on the rest of its islands. This makes it the monster with the lowest bed count on Ethereal Island, outside of Dipsters.
