In this game, based on the children's song about the old woman who swallowed a fly, players choose from a selection of creatures, each trying to catch the one selected by the other player. Whoever catches the most of the opponent's creatures, or plays the most that don't get caught, will be the winner. The game is played with two mini-decks of nine cards, one for each player. Each deck contains cards representing creatures from the song: the horse, cow, goat, dog, cat, bird, spider, fly, and the old woman herself.
