SpongeBob and Patrick are with Sandy as she tests her new invention that can send anyone to a different dimension when they walk through the portal that her wheel produces. Sandy needs to go get something from her house, so she warns SpongeBob and Patrick not to touch anything. Despite her warnings, the two wildly touch every button and lever on the machine until SpongeBob hits a button that produces a portal.
SpongeBob and Patrick then go through a portal machine Sandy has created, despite her warnings and it sends them to a seemingly blank dimension. The two try to find a way out of the dimension but cannot find an exit, prompting them to panic. However, when skidding on the ground from a sudden stop of running, it makes a simple line that comes to life. This prompts SpongeBob to pull the Magic Pencil and draw a bunch of simple doodles until they realize they miss their friends. Patrick then momentarily forgets SpongeBob and draws SpongeBob, which is later revealed to be DoodleBob, SpongeBob points out the error while DoodleBob terrorizes the two by chasing them with the magic pencil.
SpongeBob then sharpens his left shoe and makes a shoe-pencil. They both fight DoodleBob with the doodles they made of their own but they later turn against SpongeBob and Patrick after DoodleBob redraws them to look evil.
He later kidnaps Patrick and brings him to a doodle castle and ties him on a flagpole. SpongeBob then attempts to rescue Patrick and fight DoodleBob at the same time. Patrick is later thrown at SpongeBob, which releases him from his rope. DoodleBob commands miniature DoodleBobs to attack SpongeBob and Patrick, with the latter eventually floating into the void of the blank dimension with other miniature DoodleBobs.
SpongeBob then doodles Doodle Sandy, which makes a portal to bring them home. After SpongeBob and Patrick are back home, the man from Texas put his hand through the portal and demanded Sandy to return his nuts. The episode ends with DoodleBob spelling "The End."
