Inside the Wolvark docks there is a Wolvark sitting on the toilet moaning about how he shouldn't have eaten that fuzzle pie. The fuzzle pie is also mentioned in various parts of the game like in the Gizzard Gulch Jail.
And I don't think that this is realy an easter egg but, it's actually possible to capture Blisterz Booty dead! Right at the baginning of the game when Blisterz is lying on the ground unconcious, go into first person mode and start punching him. He will eventually die and you can bounty him dead. (sorry if this is common knowledge but I just haven't heard anyone talk about it yet)
