SpongeBob appears in the beginning of the movie, walking out of the Krusty Krab. He looks back at the Krusty Krab to see a rocket falling down. it is aimed toward the center of the place and is spiraling. SpongeBob panics and gets a shield. However, on the way, he gets pushed back from an explosion. He looks back again to see that most of the Krusty Krab has blown up. He then runs to Patrick Star's house to get help. He explains that the Krusty Krab blew up. He and Patrick stock up on weapons and try to go fight the bombers, but he sees that Bikini Bottom is on flames! Many choppers are above, shooting the ground and blowing up stuff. Citizens are running all over the place. Bikini Bottom had become hell! Patrick goes out, and SpongeBob pops out to check on him. A bullet hits him in a hole and he gets a little injured, but he pulls it out. However, he sees a note on it that says Bikini Bottom is terrible and corrupt. He is saddened to find this, and he wonders who sent it. He realizes that it was signed as "742 Evergreen Terrace." He knows that this can not be a name, so he thinks it is an address.
