I have completed all the achievements. Got every piston skin. Bought everything from both traders. And have a 64 stack of everything. What characters am I missing? I have Sheep, Cow, Bee, Panda, Alex, Villager, Creeper, Enderwoman, Skeleton, Normal Pumpkin, Cat Pumpkin, Hornet from silksong (yes it exists in the game), SCP-1471, and Special sheep. What am I missing?
