Reach into the head of Cavity Sam to find out what's on his mind... Players receive three cards which list various "head ailments" - train of thought, block head, bright idea etc. On his turn, a player presses Sam's nose, reaches blindly into the head cavity, and has 15 seconds to locate an item on one of his cards. If he takes too long, or if the player is too rough, Sam's nose lights up and a buzzer sounds meaning the operation was unsuccessful. To add to the fun, the patient ridicules the "surgeon" with wisecrack remarks. The first player to collect all three items on their cards wins the game. The game teaches children to recognize shapes using only touch.
