Junior Squarepants-Star is an adorable baby scallop raised by SpongeBob and Patrick in the episode Rock-a-Bye Bivalve since he had no family to take care of him. SpongeBob and Patrick become the adopted parents. He eventually learns to fly in the end of the episode, leaving them while flying.
Junior apparently hates Krabby Patties, one of the few characters who does not like them. He also does not like donuts and french fries. Instead, he likes to eat worms and ice cream with worms. He also needs to have his diaper changed very often. Junior, at the end of Rock-a-Bye Bivalve, then leaps out of spongebob's window, and begins to fly, thus, making it the last time we see Junior.
Junior looks like any other scallop; he has a purple shell and has a red tongue.
