Spongebob Squarepants. He has many different shapes and forms throughout the series. He has been mostly used for comedy or gag purposes. He is seen to be a citizen who doesn't get involved in many things. He appeared in The Spongebob Who Could Fly (The Lost Episode) as a fish with many different occupations that eventually caused Spongebob Squarepants to fall from the sky in his flying pants because Jenkins, then called Cannon Ball Jenkins, shot out of a cannon and hit Spongebob's pants. He also appeared in the Main Drain as a fish that gave Spongebob and Patrick advice about the Main Drain. Not much else is known about him except that he possibly lives in Shady Shoals Retirement Home with Mermaid Man and Barnacle Boy.
