Mini SpongeBob is a small SpongeBob puppet that was created by SpongeBob. He first appears in the episode "Best Day Ever," where SpongeBob used him as a decoy to get past the guard, though he had puppet strings. He reappears at the end of "Squid Wood." He was created to replace Mini Squid, who was given a job by talent scout Milo J. Finkerfish.
Mini SpongeBob looks similar to the real SpongeBob, except Mini SpongeBob is squarer, does not have any holes, and is a lot smaller than the real SpongeBob. He also does not have a belt on his pants. Mini SpongeBob's nose is not the same as SpongeBob's, because Mini SpongeBob's nose is a small little stub, and SpongeBob's is an oval shape and longer.
