The Robot Nut Cracker is an invention made by Sandy in the episode Chimps Ahoy. At first, the robot fails do it's job which is cracking nuts. However, at the end of the episode, it is revealed that rather than cracking nuts, it is capable of peeling bananas, much to the Chimps' delight. Sandy said that this nutcracker is the best she can create and also that she cannot make a "simple" one. This was the invention which enabled Sandy's funding to be renewed, even above SpongeBob's and Patrick's invention.
