Who Did This Poo? is a matching and memory game featuring animals (and one human) and the types of droppings they make. There are 54 cards with sets of two: a card with the name and illustration of a creature, and then a card with the name + the word poo and an illustration of the type of poo they make. E.g. Rabbit and Rabbit Poo. The game can be played with any number of people. It can be played as a matching game for those who can't read, and as a memory game for those who can read. For a matching game, the cards are laid out face up and players take turns to try to match animal cards to the corresponding poo cards. If they find a match, they receive an extra turn. The player with the most cards is the winner. For a memory game, the cards are laid out face down and players take turns turning over two cards and trying to find a match. If they find a match, they keep the pair and receive an extra turn. If they don't, they flip the cards back over and play passes to the next player. The player with the most cards is the winner.
