In Barnyard Buddies, a bunch of cards depicting various animals in different colors are placed faceup on the table. Each turn, one player reveals a card that depicts four animals, each in a different color. All players race to figure out the animal and color not depicted on this revealed card, then grab the card on the table showing this colored animal combination.
This quick, mind-crushing exercise continues until the deck is depleted. Whoever collects the most cards wins!
