How to Play Uno Moo

About UNO Moo!, from BoardGameGeek:

(from back of box) Match colors or animals to get the critters back in the barn! The farm animals have come out of their barn to play Uno! Round them up by matching colors or animals. Is there a blue pig on the barn door? Match it with any blue animal or any color pig. You can also play a farmer--he's wild and matches anything! The first player to get all of their figures back in the barn wins.
