Do you mean in a role play/character making way? Because I don’t see any new B variations in the pixdex... So officially not every pixpet can, but as characters I’m you can probably make them whatever color you want (or lack of, in the case of albinism/amelanism)

@Chibimieze
it was an april fool starting on discord. Not all players were aware of it. They just photoshop the albino pydeer under their pet bio to make it like they have it. You can always check in their house to see that they don't have that pet though.

@AlphaLeo000 is a master illusionist xD

I did and he's still on my profile! Will probably remove him soon though lol

Though if that is the case hen there can be a melanistic counterpart to some pets, though i wouldn't mind a black shluppbunn looking fellow or a Black Drax
