Not soon after, a blob of goo falls on its head, resulting in him too being corrupted. They venture to Amity Park, where Morphoid asteroids rain on the citizens, freeing the Ghost Dog in the process. They retrieve the first piece of the Vessel, while more goo falls on SpongeBob, and at the lair becomes a puppet of sorts for the Morphoid supreme leader. He soon tires out of attacking the heroes, and is then beat up out of being possessed. Bitters, Gaz, and Professor Membrane, then face the corrupted Gir, who has sprouted several mechanical tentacles and has the ability to summon Morphoids from his very being. The next world they go to is Zim's town, where Gir has been corrupted by a taco. At the lair, he becomes a vessel for the leader of the Morphoids while the Wise Old Crab informs them that a huge robot called the Vessel of Portentia is hidden in the Mawgu Lair, and requires four special components to power it up. They defeat this new menace by feeding him Krabby Patties (which ironically turned him into a zombie in the first place a drop of Morphoid goo fell on it).
They go through Bikini Bottom, where the group battles an army of Morphoids, free Gary, Squidward, and Patrick from the goo, and finally confront the corrupted Bubble Bass, who has grown to enormous size. Meanwhile on the evil side, Technus receives an arm blaster, Plankton is given a hammer that allowed him to grow (about to the height of Jimmy, Zim, and SpongeBob), Traloc receives a pouch of magic potions, Dib is given a gun-like balloon launcher, and Beautiful Gorgeous receives a heart-shaped megaphone. Jimmy is able to figure it out, and fits everyone with weapons fitting their personality: Jimmy receives some sort of helmet and a tennis racket, SpongeBob gets a bubble blower, Danny receives a device that allowed him to partly clone himself, Tak is given a staff, and Zim receives a plunger (or as he refers to it, "It is a Plunger of DOOM!!!"). They make a plan to stop the gooey creatures, identified as Morphoids, when the Wise Old Crab arrives to inform them about the technology in the lair. Zim and Dib then arrive, with Zim joining the good guys, and Dib joining the Syndicate. SpongeBob and Patrick explore the vast Mawgu lair, where they meet Danny Phantom and Tak again and the new Evil Syndicate composed of Technus, Beautiful Gorgeous, Traloc, and Plankton. Soon, the gooey creatures spawning from the asteroids start taking over Bikini Bottom. Jimmy Neutron then arrives to take them to the Mawgu lair. He becomes a zombie, chasing SpongeBob around the perimeter of someone's house until Patrick intervenes. A huge drop of goo falls on Squidward, causing the top part of his face to turn orange and become a cyclops of some sort. One seemingly normal day, SpongeBob and Squidward are on their way to work when huge asteroids start raining down on Bikini Bottom.
