punishing_bird
A small and very cute white bird from the Project Moon universe. Don’t piss it off, or it will reveal a nasty surprise: a_massive_maw_extruding_from_the_red_spot_on_its_tummy.
It is one of the three Bird abnormalities, along with Judgement Bird and Big Bird (project Moon). If all three are out and about at the same time, they’ll wander towards a gate that spawns, wherein they’ll fuse into the secret fourth Bird abnormality, Apocalypse Bird.
