In the movie, SpongeBob and the gang (like Jimmy, Timmy, B.O.B., Jenny, XJ-4, Sheen, Chester and Patrick) met the new friends like a toaster named Toaster, a blanket named Blanky, a lamp named Lampy, a radio named Radio, and a vacum cleaner named Kirby awake in a cabin in the woods to find their master gone. They hear a car outside but when Blanky looks out the window he notices that the car is leaving and goes to get a picture of the master and begins to cry much to Kirby's disturbance who tries to grab the picture from Blanky which causes the frame to break but the picture isn't broken. They soon come face to face with Air Conditioner who is mean to them because the Master never played with him like he did them that he tells the Gang that the Master isn't coming back and then he blows up in angerness. Soon the gang hears another car approaching but when they look out the window together they find out that it's a Real Estate Man putting up a FOR SALE sign and now they know that the Master is gone. The Toaster decides that they should go to the city and find the Master. They've get a luxious bus (from Atlantis SquarePantis) that they travel with it. That night they camp in a clearing. Blanky tries to snuggle up with someone but noone will let him snuggle up with him so he goes to sleep sadly with noone to snuggle up to. The next day they come to a meadow where they meet a bunch of animals who fasinate their reflections in Toaster and some mice befriend Blanky until they try to pull him down a hole and try to eat his picture of the Master. Shortly afterwards they continue their journey and travel into a dark forest where they camp. Later, SpongeBob and Toaster are chased by Bigfoot during a fishing practice session involving SpongeBob's Perfect Cast technique. Trapped in the bus by Bigfoot, who has the bus keys, SpongeBob, the gang and the appliances spend the night in the bus and which Toaster remainds Lampy of the time when his bulb burned out and the master put in a new bulb and Lampy just glew. That night SpongeBob and Toaster has bad nightmares that a Firefighter Clown kidnaps their Master and that Toaster falls into a bathtub (Toaster's Nightmare) and that Plankton have to steals SpongeBob's heart (SpongeBob's Nightmare). When SpongeBob, Toaster and the gang awake it's raining and Blanky gets blowing out of the bus up in the trees and the gang can't see him because of the darkness and XJ-4's tube (she saves Lampy's life before his bulb explodes) goes out. The next day the gang still searches for Blanky and finds him up in a tree nearby and Kirby rescues him. As they continue their journey they come across a bridge and street, not too happy with this, SpongeBob angrily stops the bus at a mountain viewpoint but forgets to put the brakes on, which causes the bus to go onto the road when Toaster leans against it. As SpongeBob, the gang and the appliances pursue the bus down the road, eventually landing in a river on the bus (expect Kirby are gets out before they land). Kirby jumps in and saves them all. When he brings them ashore Toaster walks away sadly because he believes that he's gotten the gang lost but comes back to help pull Kirby along but as they do Kirby falls back into the water and sinks as do SpongeBob, the gang, Toaster, Blanky and Lampy. Just as Radio is about to do the same a man named Elmo St.Peters pulls SpongeBob, the gang and the applances out and puts them into the back of his big red pickup truck and takes them to a parts store. Once there they meet an Old TV who gives XJ-4 a new tube and tells them that StPeters is quite an amazing fellow. The gang watch in horror as StPeters takes a blender apart and sells it's motor to a costumer. Knowing what their fate is the gang try to escape but StPeters comes back and tries to take Radio apart to sell his tubes to the same costumer who bought the blender motor. With an idea from Lampy the gang manage to scare StPeters and knock him out, rescue Radio, and escape the parts store as do the other applances who were all ready in the store. Meanwhile Ron the Master is living in an apartment in the city with his Mom and is packing to go to college. His girlfriend Cindy comes to pick him up to take him to the cabin and pick up the radio, toaster, blanet, lamp, and vacum cleaner so Ron can use them at the dorm at his college. Shortly afterwards the gang arrives at the apartment but find out that the Master isn't there and decide to wait for him there. The other applances in the apartment are jealous of the Master's likes for SpongeBob, the gang, Toaster and his friends and throw the gang into a dumpster to Ernie's Disposal hoping they will get taken to the dorm by the Master. At the cabin the Master doesn't find the applances but manages to fix Air Conditioner who comes back to life happily and the Master returns sadly to his apartment in the city. At Ernie's Disposal which turns out to be a junkyard the gang watches in horror as a Giant Magnet picks up old cars and puts them on a machine that crushes them to peaces. At the apartment the Master sees a commercial for Ernie's Disposal on the Black and White Television and has Cindy take him there. Once there the Master finds SpongeBob, the gang, Radio, Kirby, Blanky, and Lampy but just as he's picking them up the Giant Manget picks him and the applances up and puts them on the machine but just as the machine is about to crush them Toaster jumps on and manages to stop it. At the apartment Ron fixes Toaster and puts him and the other applances in Cindy's car and they head off to college. SpongeBob and the gang wave goodbye to the applances are happy they completed their mission and found the Master and they can't wait to have more adventures at the Master's College.
