My Singing Monsters

Towards the end of the year, the plump and pleasant Yool schedules a relaxing sojourn on Cold Island. Its arrival is heralded by the jingle bells dangling from its antlers, and the booming resonance of its voice. Just being near a Yool produces feelings of peace and joy, so the other Monsters always try and convince it to stay the whole year round.
Monster Bio

Description[]

Yool is a Seasonal Monster that celebrates the Festival of Yay season and is found on Cold Island. It was added on December 6th, 2012 during Version 1.1.0. As a Seasonal Monster, it is only available at certain times. It is best obtained by breeding Thumpies and Congle. By default, its breeding time is 1 day and 12 hours long. Although Yool does not have good Coin production when collecting once per day, when collecting multiple times it can rival other Monsters such as Ethereals or Quad-Elements.

Yool can be teleported to Seasonal Shanty once fed to level 15. Yool has a decent Coin production compared to other Monsters on Seasonal Shanty.

Song[]

Audio samples:

Vocal (Memory Game; Cold Island):

Jingle Bells (Gold Island):

Voice actors: Dave Kerr (Cold and Gold Island), Eric De Val (Shanty)

VSTs[]

Virtual Studio Technology is an audio plugin software that has libraries of sound effects and synthesized instruments. Within these libraries are SoundFonts, which are the individual effects and instruments themselves. The Monster-Handlers utilize several VSTs to create the sounds of instrumental and sometimes vocal Monsters.

Breeding[]

On Cold Island, Yool can only be bred for a limited time during the Festival of Yay event or Out of Season promotions:

On Seasonal Shanty, the only way to get a Yool without already having another Yool on the island is through teleporting.

Any breeding combinations containing a Yool may fail, and give one of the parents as a result. However, breeding a Yool with an Aux. Seasonal is preferable, as it has a higher chance of getting another Yool than that of getting an Aux.:

Out of these, Yool + Monculus is the best combination, as it has the lowest waiting time in case of not resulting in another Yool. Yool + Spurrit and Yool + Gobbleygourd are also good choices.

The Rare variant of any breeding Monster can be used instead of the Common variant.

However, on Seasonal Shanty, the best way of getting a duplicate Yool is by breeding a Common Yool with its Rare variant, with a 100% chance of getting it if the Rare variant is not available:

On September 12th, 2014, the breeding combination for Yool was changed. The old breeding combination for Yool (Deedge and the Thumpies) was one of the combinations for Grumpyre, but since they both had the same breeding time, it was impossible to distinguish the two Monsters, as both of their speed-up times are 36 hours. The breeding combination change was made to eliminate this potential confusion.

Availability[]

For a list of when this Monster has been available, see: Breeding Availability

Yool, like all Seasonals are only available during their own season, a weekend Out-of-Season event (6 months apart) and the Anniversary Month Celebration. It is also available to breed at any time on Seasonal Shanty.

NOTE: Yool can only be bred or purchased during the available dates. Any Yools on Cold Island or The Colossingum that are obtained during that time will stay unless they are sold. However, Yool can be bought or bred on Seasonal Shanty at any time, though it is discounted when it is available on other islands. It is also obtainable via weekly Scratch Tickets on Cold Island.

Likes[]

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 won't increase its happiness by an additional amount. If there's a Unity Tree on the Island, items don't need to be near the Monster. Below are the things liked by Yool:

See the Likes page to view a complete list of all Monsters' likes.

Earning Rate and Maximum Income[]

Earning rate is in Coins per minute and depends on Happiness % (Likes increase Happiness) and Monster Level. Each Monster also has a maximum amount of income it can hold at a time. Increasing the Monster's Level also increases this limit.

Egg Consumption[]

While trying to breed other Monsters (particularly Monsters with a very low chance of breeding), the following Celestials can be used to "dispose of" Yool eggs immediately instead of putting them into a Nursery and having that Nursery not be available. Note that doing this for Rare Wublins will cause the Wublin to stop producing currency and the eggs will not expire.

Yool Egg
Yool
Adult Attmoz
Adult Attmoz
1 egg

Note that Monster eggs can only be "disposed of" before awakening Celestials; afterwards those Monsters will not accept any eggs. Also note that Monsters to which you have already disposed the number of Yool eggs that it accepts, will no longer be available as a "recycle bin" for such eggs. Also note that Seasonal Monsters, like Yool, cannot be zapped from Seasonal Shanty.

Possible Monster Names[]

To see all possible names for Yool, see Monster Names.

Notes[]

  • Yool's name is from the ancient pagan mid-winter festival, Yule, which was later absorbed into Christmas. Yule is short for Yuletide.
  • Unlike most Monsters, Yool only likes two Decorations (on Cold Island), the Crumpler Tree and the Piney Tree. The same goes for Shugabass.
  • Yool made an unofficial appearance in the Market during the Easter 2013 celebration, where it was available for purchase but without confirmation of successful breeding attempts. Officially, Yool returned Out of Season from April 30 until May 7, 2013 at noon ET, with confirmation that it was available by breeding or purchase with Diamonds (at an inflated price of 225).
  • On December 2nd, 2015, Yool was on sale for 75 Diamonds, and was available for early access for 24 hours.
  • On June 24, 2016, all Seasonal Monsters, including Yool, received an element. This addition of elements to Seasonal Monsters was not yet available in-game, but was shown on a post My Singing Monsters put on social media. Each element design is based on the holiday the Seasonal Monsters are based off of.
  • So far, Yool has the second-highest breeding time amongst Seasonals, with the highest being Jam Boree.
  • Yool was the first Seasonal to be available on The Colossingum. It was also the first Seasonal to have an Epic variant.
  • Until Ffidyll was released and added the new verse, Yool used to play through the entire song on Seasonal Shanty.
  • Before November 9th, 2022, it was possible to breed Yool on Seasonal Shanty using any combination of two Aux. Seasonals.
  • Like real world deer, Yool typically sheds its antlers between January and March, which is why it is not really seen that often around that time because it is very self-conscious about its appearance.
  • Yool was seen in an announcement for Bonus Items.
  • The amount of beats Yool sings for doubles with each Island:
    • Yool sings for 32 beats in total on Cold Island.
    • Yool sings for 64 beats in total on Gold Island.
    • Yool sings for 128 beats in total on Seasonal Shanty, excluding when Yool only plays the sleigh bells.
  • The exact date of Yool being added to Gold Island is currently unknown.
  • Yool is the only Core Seasonal to be on two Islands with rhyming names (Cold Island and Gold Island).
