The Worm from Appleworld lived in an apple under the sea. For his brief appearance, in Rock-a-Bye Bivalve, he happily greeted SpongeBob and other fellow sea creatures before being pulled from his apple home and eaten by Junior, a baby scallop. He only had two lines before being eaten.
"Hello Sea Creatures! I bring you greetings from Appleworld!"
(slowly being pulled from apple hole)
"Huh? Wait! We will bury you!!"
