Bloonicorn is a skin that can be applied to the Unicorn, and is unlocked after you have popped a total of 20000 bloons with Unicorns. It takes two different forms, which the game chooses randomly when you place a Unicorn. One of these forms makes it look like the Unicorn is made up of a large number of different-colored bloons (from horn to tail, the colors make a rainbow). The other form makes the Unicorn look like a unicorn balloon animal, and is multicolored, but not a rainbow. After being earned, this skin can be turned on or off before starting a game. It can be used at the same time as most other skins.
