In the Operation game, kids get to be the doctor and make Cavity Sam better or get the buzzer! Perform successful action noted on the cards by picking funny ailment pieces out of the game tray with a pair of tweezers. But watch out! If the tweezers touch the sides of the openings, the buzzer goes off and Cavity Sam's nose lights up! Then players look for their Specialist card that fits that action to earn an even higher fee. The player with the most money after all of the Funatomy parts have been removed wins the game! Hasbro Gaming and all related terms are trademarks of Hasbro.
