Munchkin: Petting Zoo

From Steve Jackson Games:

Ah, the good old petting zoo.
Where else can you find adorable animals, screaming children, and the most awful smells?

Munchkin Petting Zoo lets you add a menagerie of surprisingly friendly fauna to your arsenal! But you should probably still wash your hands after you pet that . . . giraffe?

This an expansion for Munchkin. It is not a stand-alone game.
