Costumes

This article is about the game mechanic. For the Colossingum decoration, see Costume Rack.

Costumes are cosmetic changes for monsters that can be purchased in The Colossingum or main islands. Before the introduction of the Colossingum in version 3.0.0, costumes used to be a limited time appearance change applied to all species of monster on their native islands during Yay and Spooktacle. But since Spooktacle 2021, these types of costumes have been phased out in favor of the new, purchasable ones that stay with your monsters forever. Costumes are also now available for other seasons, like SummerSong, which didn’t have costumes in the original iteration. Before version 3.0.4, costumes from The Colossingum were not available on other islands.

Costumes can be bought on the main islands with Coins or Diamonds to change a monster's appearance. In Version 3.2.0 onward, they can also be obtained through breeding monsters. Once bought, these costumes will stay permanently unlocked, no matter if they were available during a limited time or not. Monsters wearing costumes will still keep their costumes when teleported to a different island.

Colossingum costumes don't only change the appearance of a monster but can also give the monster wearing it a new attack (tune) in place of an old attack that the monster inherently knows, or sometimes a new move altogether in some cases, although this is not the case with all costumes, some are still just purely for aesthetic pleasure. Some costumes are unavailable to The Colossingum and exclusive to the main islands, such as costumes owned by Ethereals, Dipsters and Werdos.

During a Seasonal Event, a special set of costumes will be available, and these costumes will be part of their own seasonal series.

Be careful, once you have used a free costume on the Colossingum, you will have to pay currency or earn the costume a second time if you want it on another individual (of the same monster species).

Legacy Costumes

From 2012 to 2020, Monsters only dressed up for the Halloween/Spooktacle and Yay/Christmas seasons. Costumes were applied to all monsters for free and dissappeared after the seasonal event was over.

Notes

• Since 2017’s Spooktacle, all monsters who dress up will dress up immediately on the day the corresponding celebration starts.
• Monsters will have their costumes available for the Festival of Yay, Spooktacle, Feast-Ember, SummerSong, Season of Love, and Eggs-Travaganza even if they don't appear on the island that the celebration is centered around.
• On October 30, 2014, the Spunge also put on a costume, dressing up as a vampire. This was the result of a contest in which game players sent in costume ideas, with the winner being used in the game. The drawing became Spunge's Vampiric Veneer costume, which is now used in game.

  

  The original plan for the Halloween Spunge

• The Spunge did not change appearance for the Yay season after 2013.
• The Mammott, Epic Mammott, Shrubb, Rare Shrubb, Furcorn, Rare Furcorn, Epic Furcorn, Epic Maw, Bowgart, Rare Bowgart, Epic Bowgart, Spunge, Pummel, Rare Pummel, Thumpies, Rare Thumpies, and the Dipsters are the only monsters which have changed their appearances for both Spooktacle and Yay.
• Shrubb, Thumpies, and the Dipsters are the only monsters who have dressed up for Spooktacle, Yay, and SummerSong.
• There is no costuming currently associated with Anniversary Month, Beat Hereafter, Crescendo Moon, Cloverspell, or Echoes of Eco.
• During Spooktacle 2015, some players experienced a glitch in which certain monster's costumes would be jumbled around, along with the Plant island.
• Until October 2015, Ethereal Island was unaffected by holidays, as it had no holiday of its own, and none of the costumed natural monsters could reside there.
• During Spooktacle 2017, there was a glitch on Composer Island that made Reedling's eyes, nose and mouth appear outside of it's Smunkin Mask.
  • This same glitch happened when costumes were first made available on Fire Haven. Reedling's eyes and mouth went through its Breath Tweeter and Oni-rous Mask costumes during its playing animation.
• No Natural or Rare Natural monsters dressed up for Spooktacle or Yay the year of The Colossingum's release.
• In version 3.2.0, the shop icon for the costumes section contained a disco ball that at the time wasn't revealed. It was later revealed to be the Take Me To Thumpie Town costume for the Thumpies in SummerSong 2021.
• Some Colossingum costumes in the Steam version have some differences from the mobile version.
  • PomPom's Pom-Mohawk costume has more detail.
  • Congle's Monster Mothma is more saturated, and used to be brighter before version 3.2.0.
  • T-Rox's Guilded Pauldrons has bigger indents, and 2 extra indents.
  • Riff's Spiny Six Strings has a broken horn, an extra small horn, and an ear added on it's guitar.
• All Seeing Belly, Growth Spur-ts, Infamous Mug Pot, Pad Hair Day, Bubble Whammy, Parasol-ing, Miner Key, In It To Fin It, Fantasy Wings, Tentacool, and Beach Bum are the only animated costumes.
