Nicktoons Unite!

Nicktoons Unite! (known as SpongeBob SquarePants and Friends: Unite! in Europe) is a 2005 video game featuring characters and levels from SpongeBob SquarePants, Danny Phantom, The Fairly OddParents, and The Adventures of Jimmy Neutron: Boy Genius. The gameplay of the console versions is quite similar to X-Men Legends albeit more simplistic, and with a larger emphasis on puzzles.

Story
When Professor Finbarr Calamitous steals Jimmy Neutron's plans for the Universe Portal Machine (in GBA & DS version Neutronic Reality Projector), he constructs his own version of the device to recruit an inter-dimensional band of villains made up of Vlad Plasmius, Sheldon J. Plankton, and Denzel Q. Crocker. Known as the The Evil Syndicate (in GBA & DS version The Syndicate of Evil), they create a Doomsday Machine (in GBA & DS version Doomsday Device), while unleashing an army on the worlds of Dimmsdale, Bikini Bottom, Amity Park, and Retroville.

"Brain-blasting" a plan, Jimmy uses his Universe Portal Machine to scour the multiverse for, drafting Danny Phantom, SpongeBob SquarePants, and Timmy Turner. Now the Nicktoons must defeat The Evil Syndicate and destroy the Doomsday Machine.

Gameplay
In console version player can play with three computers and no other human players, or with a friend or two with the remaining computer(s). One can switch abilities, which have multiple uses. For example, if four people are playing, a path full of enemies could be crossed with Danny's Ghostly Wail, Spongebob's Bubble Bombs, Jimmy's Quarterback Gear, and Timmy's Remedy.

The difficulty and length of the game becomes greater with multiple human players. If there is at least one computer, a certain button can be used to Regroup with computerized team member(s).

There are also things only a certain character can do. For example, SpongeBob is needed to use Bubble Bombs to blow up a pillar, Danny is needed to use Ghostly Wail on some glass, Timmy is needed to use Freeze Glove to freeze some water, or Jimmy has to shoot down some things with his Neutron Flare.

At one point of the game, the player has to cross over a hole with Danny, who can hover when in Phase Shift, and then have SpongeBob toss over a Bubble Bomb. Danny must then pick it up, and throw it at a crack in the wall to find a lever. This is extremely difficult when done alone.

Goddard can be found in all four worlds so he can upgrade the players weapons and abilities.
