It is a typical day at Goo Lagoon and SpongeBob and Patrick are having fun playing on the beach. Suddenly, large purple, goo bubbles arise out of a volcanic crack at the bottom of the lagoon. Two of these bubbles approach SpongeBob and Patrick while they are about to drown at sea. They bounce the goo bubbles like a ball on seawater, accidentally hitting some fish swimming with a floater, a surfer, and a cheerleading-style posed fish. Meanwhile, Plankton tries to sell his chum from a wheelbarrow when Squidward smashes him with an umbrella. SpongeBob and Patrick use their Mucus Bubbles to likewise bounce and smash Squidward and his belongings. Plankton thinks that it is Karma and he notices that SpongeBob and Patrick are bouncing the goo bubble like a ball. He doesn't know what it is and tries to ask Squidward but Squidward leaves him and angrily scolds SpongeBob and Patrick. Soon, Sandy approaches them. Sandy tries to explain to SpongeBob, Patrick, Squidward, the Bikini Bottomites, and Plankton, that the bubbles are made of a highly toxic "Super Goo". She explains that they are safe when stable, but as is, they are very unstable, and if popped, they can coat a large portion of Bikini Bottom in purple goo. Plankton hears this and unveils a multi purpose ship which he uses find the crevasse and produce a bubble large enough to cover the entire city, as most are rather small (about the size of beach balls). Then he goes under the lagoon in a ship to find the crack where the bubbles are coming from.
Meanwhile, more bubbles begin to arise from the lagoon, and the Bikini Bottomites begin to use the bubbles. Although Sandy said that they were dangerous, SpongeBob and Patrick continue to use the goo bubbles as bouncy balls. Squidward begins to use the goo as a hairdo. The other citizens continue to use it for their own purposes as well. Perch Perkins begins to report for the Bikini Bottom News with Johnny. He states how the Goo Bubbles are popular at Goo Lagoon. While on the air, Sandy, now going partly insane with her theory, once again tries to warn them to stop playing with the goo. Again, nobody believes her. Plankton continues on his quest to put the goo to use, determined to find the crack at any cost. Soon, he does find it. Plankton, as well as Karen, widen the crack and unleash the largest Goo Bubble yet. It rises out of Goo Lagoon, finally convincing everyone to evacuate the beach.
The trio examines the bubble and realizes it is dangerous. They need to stop it with supplies from Sandy's treedome SpongeBob, Patrick, and Sandy proceed to her treedome. However, Patrick gets swept into the bubble. The duo gets into Sandy's submarine at her treedome, then proceeds to save Patrick. They soon find the giant bubble and they tell Patrick to get in the Submarine but Patrick refuses, so they send down a crane to grab Patrick, who is sitting on the goo. Patrick is pulled into the submarine, and then the three prepare themselves to stop the bubble. They soon discover that Plankton is controlling the bubble after they see his ship. The recently reunited trio pursuit Plankton around the bubble. They catch him rather easily. Sadly, its revealed to be a trap; Plankton outsmarts the trio and sends them off the bubble. To rub salt into the wound, Plankton also destroys Sandy's submarine. The trio then pursues the Plankton on foot through downtown Bikini Bottom.
They end up at the Krusty Krab. SpongeBob, Patrick, Sandy, many Bikini Bottomites, and Mr. Krabs confront Plankton and the bubble in front of the Krusty Krab and Chum Bucket. Spongebob attempts to send the bubble away via creating a massive "Bubble Bruiser". The attempt, however, backfires. Plankton once again demands that Mr. Krabs hands him the Krabby Patty formula or else he will pop the bubble, and leave the entire city covered in purple goo. Left with an ultimatum of giving up the formula or either having an angry mob destroy the Krusty Krab and do it themselves, or having to spend an extended period of time cleaning Bikini Bottom, Mr. Krabs reluctantly surrenders and gives him the "formula." However, Plankton, in the ultimate act of welching, pops the bubble anyway, causing the entire city to get covered in purple goo.
Plankton gets away and proceeds to read the "formula " on his ship. It reads, "Just one Ingredient...". He quickly realizes the formula is fake when he pulls down the paper, revealing a stick of Dynamite. The Dynamite stick explodes, causing his ship to crash into the roof of the Chum Bucket. Mr. Krabs, covered in goo, laughs at Plankton's comeuppance. Sandy reminds him that everyone and everything in Bikini Bottom is still covered in goo. However, Mr. Krabs tells her that even in a worst-case scenario, he can still make a profit. He creates a cleaning vendor where they are cleaned by a second "Bubble Brusier" created by Spongebob.
