In SpongeBob's dream, the player is in a race. First, the player has to complete a lap on a race course dotted with enemies, avoiding tires, oil cans and ferocious cones. Then, in his nightmare, the player has to try to navigate and get out of the Jellyship, by sneaking past the Alien Jellyfish Guards so the player can get the net launcher from Gary, which allows the player to find 3 keys to open the door and rescue the player's friends who are locked up in it.
In Patrick's dream, the player takes place in Downtown Bikini Bottom. First, the player has to defeat the Door-to-Door Salesmen, Dental Hygienists, and Personal Trainers in Bikini Bottom. Then, the player has to shoot the Flying Clowns and battle a Bigger Clown, high in the skies. Lastly, the player has to navigate through Patrick's house without his superpowers (instead, with a handheld vacuum equipped) and defeat the Dreaded Patrick.
In Plankton's dream, the player takes place in Bikini Bottom. First, the player has to destroy the buildings, homes, the Krusty Krab, Barg'n-Mart, and Krabzilla as a giant 1000-foot tall monster.
