The game begins the same way the episode does in which an artist at sea drops not one but two pencils into the sea where at the time Patrick is walking around. Returned to its original two-dimensional form, DoodleBob smiles and SpongeBob hangs the drawing in his living room. However, DoodleBob is foiled when SpongeBob notices the doodle's foot fusing to a sheet of paper and uses another within a book to entrap DoodleBob. He redraws himself, but clumsily loses his half of the pencil when he flings it.
While DoodleBob does succeed in erasing half of SpongeBob, the sea sponge grabs the pencil and causes it to break. DoodleBob then declares its intention of taking SpongeBob's life for its own and pursues SpongeBob while erasing portions of his house. Climbing up the stairs, it reaches his bedroom and reclaims the pencil to redraw its body. In his fury, SpongeBob overlooks an arm that inches towards SpongeBob's house. However, SpongeBob manages to get a hold of the pencil and violently erases DoodleBob when the drawing runs into a rock during its attempt to flee. DoodleBob throws SpongeBob to the side and conks Patrick on the head with a rock. They come across DoodleBob babbling and brandishing the pencil in an empty field, likely in the midst of it trying to recreate something else. When the two approach, DoodleBob delays them with a pit trap and runs off again. SpongeBob and Patrick find DoodleBob in a poorly drawn sketch of SpongeBob's pineapple house. The prank goes awry as Doodlebob swings Squidward around and then runs off with the pencil. After experimenting with drawings that come to life, such as a jellyfish and Patrick's crude rendition of Squidward, the two decide to play a prank on Squidward by having a crude doodle of SpongeBob knock on his door. SpongeBob examines the pencil and begins to doodle with it. His pencil lands near SpongeBob's house, causing SpongeBob and Patrick to panic. The episode starts off showing an artist at sea working on a new piece when he drops his pencil into the ocean.
