The Worm from Appleworld lives in an apple under the sea. He appears in the episode "Rock-a-Bye Bivalve."
He is a pale purple colored worm with black eyes and a white tongue.
For his brief appearance, he happily greets SpongeBob and other fellow sea creatures just before being pulled from his apple home and eaten by Junior, a baby scallop. He only has two lines before being eaten.
His quote before being eaten, "Huh? Wait! We will bury you!" is a reference to a quote famously said by Soviet premier Nikita Khrushchev.
