Some monsters occupy multiple beds. When you need more beds, upgrade the castle.

Description

The Castle is a Structure that allows for Monsters to be placed on an Island - each castle provides a certain number of beds for monsters. Aside from Gold Island, Wublin Island, Tribal Island, and Celestial Island, each island starts with the same Basic Castle and the progression through the castles is the same, with the same number of beds for each level of castle (the number of beds per castle is increased on Ethereal Island, due to the fact that Ethereal Monsters occupy large numbers of beds), but the time and cost required and Experience granted for each upgrade differs based on the island. Gold Island has a single castle - the Crystal Castle - which does not have a bed limit, and cannot be upgraded.

There are two mini-games that you can play from the Castle; you can learn more about them by clicking on the links below:

Song

The upgraded Castle (i.e. any upgrade that is not the Basic Castle) produces an electric bass sound. This does not happen in Shugabush Island as the Shugabass replaces the Castle's musical role. No bass sound can be heard in Gold Island though. In Fire Haven, Fire Oasis and Psychic Island, it plays a bass/sub-bass synth. In Faerie Island, it plays a baritone synth.

Common Castles

In the following table, the number of beds shown is given as the number on all islands except Ethereal, followed by a slash and the number of beds on Ethereal Island.

Castle Image Castle Beds
Basiccastle200.png Basic Castle
Singing takes a lot of energy, and monsters need sleep! The Basic Castle really isn't very comfy at all; the rain gets through, it's drafty, and cramped.
4/20
Modestcastle200.png Modest Castle
It's great to have a good night's sleep! The Modest Castle is dry and warm, but small.

Comfycastle200.png Comfortable Castle
Ah, some elbow room! The Comfortable Castle even has indoor plumbing.
18/80
Spaciouscastle200.png Spacious Castle
The Spacious Castle has lots of room for monsters to relax and refresh.

Luxuriouscastle200.png Luxurious Castle
It just doesn't get any better than this! The Luxurious Castle has everything a monster might enjoy, from cold slime pools to dark, nasty dungeons. Who would ever want to leave?

Extravagant Castle.png Extravagant Castle
This state of the art domicile goes way overboard when it comes to spoiling the monsters...  Personal assistants to wait on them hand and foot (at least those that have hands and feet), the spiffiest sound systems on the monster market...  They've got it made in the shade.

Paradise Castle.png Paradise Castle
After agreeing that more beds equals more fun, the monsters set out to create the most capacious castle ever - and what better inspiration than Gold Island's own Crystal Castle? Following extensive study of the original architectural marvel, the multiverse's finest architects were tapped to craft the new castle in its image. After the smoke cleared, there was no question - this is the be-all and end-all of monster living arrangements. Welcome to paradise!

Crystalline Castles

Crystalline Castle upgrades were added in the 2.4.1. update and are only available on the Natural Islands. These upgrades allow at least one of each monster to be on the island at once. And the bed space at maximum is 180. Each castle is unique, sporting the color and features of the island, as well as the element it represents. They also have the crystals from Dawn of Fire (when the islands were simply the elemental lands of the continent) on the top of their pillars. It was also stated they were built using those crystals. Each castle has the crystal they had for the elemental lands the island represents: Plant island’s crystalline castle has vegidian crystals, Cold island’s has frozium, and so on. The order from bottom to top of these crystals is 3 natural crystals, (first seen level 1) 2 polished crystals, (first seen level 2) and 1 carved crystal. (level 3) each islands crystalline castle costs 20 more diamonds than the last islands castle, and each next level costs double the current level. (Plant Island’s castle takes 80 diamonds for level 1, 160 for level 2, and 320 for level 3. Cold Island’s take 100 diamonds for level 1, 180 for level 2, and 340 for level 3. This keeps going up throughout the islands)

Thanks to mineralogical acumen supplied by Fire Monsters, Plant Island's residents knew exactly where to dig to find vast deposits of Vegidian, a crystal once found in abundance back when the island was an Elemental Land of the prehistoric Continent. Combining the raw strength of the crystal with modern lapidarian techniques has resulted in this magnificent Castle, furnished with more Beds than ever before.

Although shaped like a castle, this mysterious structure actually serves as the main power generator in the monster dimension of the multiverse!  It's from here that monsters derive their musical inspiration, as well as their tireless energy so that they can keep singing forever!

Composer Island
Composer Castle.png Composer Castle
The Castle on Composer Island is styled after another famous Structure in the Monster World, but the similarity is more than skin deep! Just as the Crystal Castle serves as a power generator for Gold Island, the Composer Castle acts as a powerful transmitter for the creative energies flowing in from the human universe - it's go some of the Seam's best upload/download speeds!


Note: Monsters on Composer Island only take up 1 Bed except the Glowbe, meaning a total of 40 Monsters can be placed, while Glowbes, infinite.

Notes

  • When first introduced, the Extravagant Castle had a maximum of 52 beds. However with the update to version 1.1.3, the maximum beds was increased to 60.
  • The castle on Shugabush Island does not produce any bass sound. Instead, Shugabass produce a bass sound.
  • The Vita version of the game currently does not include the Paradise Castle. However, the PC version does.
  • For a long time, there was a hint of a new castle being added. The hint could be viewed from the log-on screen hints and tips. It said, "The Extravagant Castle is the Maximum Castle. For now."  This hint has now been realized in the Paradise Castle.
  • Costs for Extravagant and Paradise Castles in Water and Earth Islands increased after the Anniversary Month Celebration ended in 2014. Instead of each of the Extravagant Castles costing 30 Diamond25px.png, they now cost 35 Diamond25px.png in Water Island and 40 Diamond25px.png in Earth Island. The Paradise Castles cost 70 Diamond25px.png and 80 Diamond25px.png respectively.
  • The castle on Ethereal Island has more beds than the natural islands, due to the fact that Ethereal monsters take up more beds than usual.
  • The castle on Composer Island is a Paradise Castle with only 40 beds. However, all monsters in the Composer Island, except the Glowbe occupies one bed. (Glowbes occupy zero beds)
  • Although the game states that Monsters sleep in the castle, they do not go to sleep by themselves, and when muted do not go into the castle.
  • The Castle on Psychic Island was the only non-upgraded Castle to play sound. It was confirmed by the Monster-Handlers to be a bug and was later fixed.
  • The Crystalline Castles were added to the game on June 3rd, 2020. They are based off of the Crystals from Dawn of Fire. The Crystalline Castles are likely not called Crystal Castles to avoid confusion with Gold Island’s Crystal Castle.
  • Upgrading to a Crystalline Castle presents a warning reading "Warning: Using the maximum number of Beds in the next Castle upgrade may result in some sound and performance issues on older devices. Continue?"
