Tower of Cows is a Print'n'Play dexterity game available from the pbskids.org web site. The players stack cows, which are constructed from cardstock folded tent style. Each turn a player draws a card which tells them how many cows to stack and sometimes gives instructions like "Stack 1 cow while singing Happy Birthday to Moo." If a cow drops, the player gets a penalty point. The game is based on a game mentioned in the PBS show Arthur, and is located in the Arthur section of the web site, but does not have any Arthur related art on it.
