The Reindoonicorn is a cosmetic item for all classes. It is an inflatable reindeer-unicorn based on the Balloonicorn that floats behind the player. This item may only be seen in-game by users who are in Pyroland.
When equipped, players are able to see in Pyrovision; map textures are replaced with those of Pyroland, gibs and pickups are replaced with their counterparts from birthday mode, other players' voices become high-pitched, and other players laugh when injured or killed.
When players equipped with this item kill an enemy unassisted by another player, the killfeed shows everyone in Pyroland that it gets the assist, with its custom name if it has one.
||The Great Deflate|
Kill 79 enemies who have the Balloonicorn pets.
