My favorite character in the first one was Trudy... wish she survived :'(. But I'd have to say Norm Spellman. He's trying his hardest & keeps going when things get rough. He never gives up. Definitely an inspiration to do your best no matter what!
My favorite scene in the SpongeBob universe is in the SpongeBob movie where SpongeBob & Patrick sing the Goofy Goober theme song. Because I'm a Goofy Goober yeah!
