Nicktoons Unite! (also known as SpongeBob SquarePants and Friends: Unite! in PAL regions) is a 2005 video game featuring characters and levels from The Adventures of Jimmy Neutron: Boy Genius, The Fairly OddParents, Danny Phantom, and SpongeBob SquarePants. In the game, the player can control four Nicktoons characters (Jimmy Neutron, Timmy Turner, Danny Phantom, and SpongeBob SquarePants) as they work together to stop an evil plan concocted by villains from each character's series. Gameplay In the console version, all four characters are on-screen at the same time. The player has the option to switch between them, with the non-selected characters being automatically controlled. The console version also offers multiplayer, where up to four players can control and switch between the characters as well. Each character has several abilities for specific situations, such as SpongeBob's pillar-destroying Bubble Bombs, Danny's glass-breaking Ghostly Wail, Timmy's water-freezing Freeze Glove, and Jimmy's long-range Neutron Flare. Jimmy's dog Goddard can be found in all four worlds, including the level that takes place inside himself, to upgrade the player's weapons and abilities. The Nintendo DS version is a 3D platformer where the player controls one of the four characters at a time, which can be selected at any moment via the touchscreen. The Game Boy Advance version is a 2D platformer in which the player must alternate between the two characters given at the beginning of the level in order to progress. It uses pre-rendered 3D sprites based on the models of the Nintendo DS version. Plot The game opens with SpongeBob discovering that Plankton is taking over Bikini Bottom with gigantic vacuum machines. Goddard exits a portal behind SpongeBob's house, and displays a message to him 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 dehydrating. Jimmy explains that his latest invention, the Universe Portal Machine, has been copied by Professor Calamitous, whom has formed a Syndicate with Plankton, Vlad Plasmius, and Denzel Crocker, and are already stealing energy from their worlds. The heroes attempt to teleport into Casper High, but arrive in Vlad's castle, where he reveals that his ghost portal is siphoning energy from the Ghost Zone, and has captured Danny's parents. Vlad knocks the group out and imprisons them in the Ghost Zone Prison. Befriending the Box Ghost, the heroes escape after
