Nicktoons Unite!

Story

The game begins with SpongeBob discovering that Plankton is taking over Bikini Bottom with giant vacuum machines. Goddard exits a portal behind SpongeBob's house and shows him a message from Jimmy Neutron. Following Goddard through the portal, he meets Jimmy Neutron, Timmy Turner and Danny Phantom in Jimmy's lab. Jimmy coats SpongeBob with self-regenerating moisture to keep him from drying out. Jimmy explains that his latest invention, the Universe Portal Machine, has been copied by Professor Calamitous, who has formed a syndicate with Plankton, Vlad Plasmius and Denzel Crocker and is already stealing energy from their worlds. The heroes attempt to teleport to Casper High, but arrive at Vlad's castle, where he reveals that his ghost portal is siphoning energy from the Ghost Zone and has captured Danny's parents. Vlad incapacitates the group and locks them in the Ghost Zone prison. After befriending the boxing ghost, the heroes escape after defeating Walker. Danny leads the heroes to the Fenton Works ghost portal and meets Sam Manson and Tucker Foley. When they return to the castle, the gang destroys the portal's generators. Danny takes possession of his father and uses his ghost gloves to beat up Vlad, but eventually escapes. The heroes then travel to Bikini Bottom and use Jimmy's air rubber to breathe underwater. Sandy Cheeks sends them to the jellyfish fields to meet Patrick Star, but he gets sucked into a jellyfish harvester. After destroying the harvesters, the group finds themselves on the Flying Dutchman's ship. Danny persuades him to let them go if he brings them back his old comrades. When they arrive at the Chum Bucket, they free Patrick and the jellyfish. On the roof, they fight Plankton, who is piloting a giant robot crab to rescue Mr. Krabs, and learn that the bad guys have been harvesting energy for a doomsday device. In Dimmsdale, the heroes infiltrate Crocker's golden fortress and turn off the power. They then make their way to the fairy world, where they meet Jorgen of Strangle, free the fairies and defeat Crocker with an exosuit on the Great Staff. The group then returns to Jimmy's lab and meets Cindy Vortex. Jimmy finds out that Calamitous has planted a flea robot in Goddard to spy on him. The heroes use Jimmy's shrink ray to infiltrate Goddard, defeat the flea robot and hack it to find Calamitous' hideout. The heroes defeat the Syndicate and SpongeBob takes out the Doomsday Machine. With Calamitous in jail, Jimmy gives the heroes each a Neutronic Recaller in case of a future incident and they part ways.
