Goomby's parents died when he was young. He did not want to get adopted, so he ran away. One day while Goomby was climbing Mt. Core, he tripped on a rock and fell off the mountain. His left cheek was badly wounded, and he soon got a scar. Goomby soon met Stevie, and they became great friends. He later met Whomparat and Flutterai.
