When SpongeBob observes this, he grabs a large book and closes it over DoodleBob, trapping him inside it and causing to become an ordinary drawing on the paper, now smiling. DoodleBob corners SpongeBob, but when he steps on a piece of paper, his foot gets stuck to it. SpongeBob and DoodleBob struggle with the pencil and cause it to break in half, SpongeBob restores himself, and DoodleBob sharpens his piece of the pencil. During a chase, he erases a portion of his house as well as SpongeBob's butt. The arm infiltrated SpongeBob's house that night and used the magic pencil to restore himself (and also adds a pair of angry eyebrows) before attacking SpongeBob.
However, unknown to SpongeBob and Patrick, SpongeBob missed one of DoodleBob's arms. SpongeBob and Patrick chased him to where he had taken residence in a crudely drawn version of SpongeBob's Pineapple house, and when they cornered him SpongeBob erased DoodleBob with the magic pencil. SpongeBob intended to use him to play a harmless prank on Squidward, only for DoodleBob to start beating him up and run away crazily, screaming gibberish. He appeared in the episode " Frankendoodle." Because he was created using a magic pencil (which belonged to a human artist at sea who accidentally threw it into Bikini Bottom, which SpongeBob and Patrick found), DoodleBob came to life.
DoodleBob was a crudely-drawn self-portrait of SpongeBob SquarePants that came to life.
