Jellyfishing - Plankton!.Jellyfishing: SpongeBob and Patrick take Squidward, who is recovering from a bicycle accident in a full body cast, on a "jellyfishing" trip (a sport involving the capture of jellyfish). When they arrive in the Jellyfish Fields, a jellyfish stings Squidward, so he goes after it for revenge. He manages to catch the jellyfish, and bangs his net triumphantly against a queen jellyfish. The queen jellyfish chases after him, attacking him with a massive sting. The next day, the bandaged SpongeBob and Patrick go to the now life-support-bound Squidward's house to apologize, only to be chased away by the jellyfish caught by Squidward. As Squidward laughs about it, he is discovered and stung by the queen jellyfish again.
Plankton!: It is mass chaos at the Krusty Krab when Plankton, Mr. Krabs' business rival, tries to steal the Krabby Patty formula for his own restaurant, the Chum Bucket. At night, Plankton attempts to make friends with SpongeBob by asking him for a Krabby Patty, but he loudly and boldly refuses and runs back home. Later that night, Plankton enters SpongeBob's head through a pore and makes his way to SpongeBob's brain. He attaches a mind control device to the brain and bends SpongeBob to his will, forcing him to walk to the Krusty Krab, get a Krabby Patty, and bring it to the Chum Bucket, where he intends to force SpongeBob to drop the Krabby Patty into an analyzer revealing the ingredients of whatever is to put into it. SpongeBob feels sorry for letting down the Krabby Patty, and his appetizing description of the sandwich causes a hungry Plankton to leap out of SpongeBob's head towards the sandwich. He lands in his own analyzer and becomes trapped in his computer Karen (he is 1% evil and 99% hot gas according to the analyzer). SpongeBob then leaves as Plankton begs for him to return with the Patty.
