"Match pairs of chihuahuas in this fast-paced fiesta of fun. Send single pups to the pound but watch out! If someone calls Andale! Andale! all of the pint-sized pooches are up for grabs. Be quick to grab the matching mutts before other players can get their paws on them. The player with the most matches wins!"

Andale! Andale! is a rummy-based children's game, players put down matches as they draw them (first player to five matches wins). To mix it up there are a few special cards (trade, steal, and Andale!). When someone plays an Andale! card, players rush to grab the pile of discarded cards that they want.
