==Synopsis==
The episode starts with Plankton planning to steal the Krabby Patty formula, analyzing a path through the Krusty Krab's air ducts. As he launches towards the Krusty Krab, SpongeBob washes the restaurant while singing the "F.U.N. Song." The water from SpongeBob's hose sends Plankton falling into a sewer, landing on Bubble Bass's toothbrush after coming out of a faucet. Bubble Bass brushes his teeth, with Plankton still on his brush, before he spits into the sink, resulting in Plankton falling down the drain.
Plankton lands at the bottom of the sewer as he attempts to make his way out, but shaking occurs soon after, revealing a sea gator. While Plankton whimpers, a large batch of chum scares the gator away. The chum reveals a group of C.H.U.M. (Collective Hive Under Master), who bow down and proclaim Plankton as their master. The C.H.U.M. leader says that they are created when Plankton flushes chum into the sewer, and the flushed chum mixes with sewer gases. The leader takes Plankton to their village, where he gets the idea of using the C.H.U.M. to help him steal the formula.
Plankton trains the C.H.U.M. for infiltrating the Krusty Krab. He asks the C.H.U.M. to batter down doors in their first exercise, function as weaponry in the second, and utilize karate against cardboard cutouts of SpongeBob, Mr. Krabs, and Squidward in the third. Although being harmed in every exercise, Plankton exclaims the C.H.U.M. as ready, before the Mr. Krabs cardboard cutout falls on him.
At the Krusty Krab, Plankton faces Mr. Krabs, as the C.H.U.M. army come out of the bathroom stalls. As the C.H.U.M. destroy the bathroom, they form a tank. The tank launches chum at Mr. Krabs, launching him towards the front window of the restaurant. He tries to ask SpongeBob for help, but he is too busy singing and playing with the hose to notice him. Mr. Krabs tries to hide from the C.H.U.M., as Plankton comes towards him on the tank, which soon forms a monster. Mr. Krabs continues trying to avoid them, but is soon caught.
As the C.H.U.M. attacks him, Mr. Krabs pledges to give up the formula, but he soon notices SpongeBob and makes a run around the outside of the Krusty Krab. While the C.H.U.M. chases him down, SpongeBob notices a penny, spraying the hose behind him, which sends Plankton and the C.H.U.M. down the sewer. SpongeBob soon notices Mr. Krabs, who praises him for saving him. At the Chum Bucket, Plankton asks to hang out with the C.H.U.M., but they prefer living in the sewer, as they flush themselves down and the episode ends.
