104b - Gone

SpongeBob wakes up one morning and finds out that Gary is missing, and discovers that he is the only one left in Bikini Bottom. At first, SpongeBob finds this hard to take. In a panic, he runs around town in a desperate attempt to find someone, only to find no soul.

When the others don't return, SpongeBob then decides to live out everyone's lives for them. He makes a bubble version of himself in his front yard, then runs to the top floor of Squidward's house, pretending to be Squidward yelling at SpongeBob for making too much noise. SpongeBob then runs to the Krusty Krab, imitating Squidward and Mr. Krabs. He imitates Sandy at the Treedome and Patrick at the Rock respectively before running to the boating school and pretending to be Mrs. Puff.

In the classroom, he realizes that living out everyone's lives won't work, and he breaks down crying on Mrs. Puff's desk. SpongeBob's mood quickly changes when he discovers a stack of blank driver's licenses. He takes a picture of himself, and prints out his own license. He then takes off with the student driver boat, naming it "Boaty," and joyriding throughout the city.

SpongeBob and Boaty become inseparable best friends. SpongeBob sleeps with the boat, and parks it inside both his house and the Krusty Krab. Spongebob is going insane without people to talk to, and Boaty realizes this. In his closet, SpongeBob has erected a statue of Patrick out of raw Krabby Patty meat, which he carries out a conversation with. The "Patty-Patrick" warns that he cannot talk because Boaty is listening. He goes crazy from the sight of any motor vehicle, and when a bus comes, he grabs a fire axe from the cinema to chop at a bus that approaches him.

To his surprise everyone in Bikini Bottom comes out of it. Mr. Krabs tells SpongeBob that everyone's mysterious disappearance was really a holiday to celebrate being away from SpongeBob for a day (according to SpongeBob, they were gone for weeks). Before venturing off, a giant effigy of SpongeBob is erected, then burned. Everyone then dances on the ashes to celebrate. Spongebob doesn't understand but soon realizes it is an honor. Patrick reccomends a "No-Patrick-Day". Everyone boards the bus except for Patrick, obviously forgetting what he just said.
