Sheep!

Fast-paced, light-hearted card game, where the object is to steal all the 'sheep' of one of four colors. The card you play determines who you get to steal from, and who gets to play next. The action jumps around the table between 4 players at increasingly fast speed, with no set pattern. You have to concentrate on what you're trying to steal, what everyone else is going for, and what you've got left, not to mention what card just got played.
