Nicktoons Snap!

Nicktoons Snap! is a Nicktoons crossover game for PlayStation Vita and Nintendo 3DS. It's a sequel to Nicktoons Freeze Frame Frenzy which was released for Game Boy Advance.

Story
Ren Höek is increasingly and furiously annoyed at many Nicktoons getting misplaced in different worlds. So he sends out Korra, Arnold Shortman, Spongebob Squarepants, Tommy Pickles, Rocko Rama and Timmy Turner to take pictures of the misplaced characters with Stimpy's brand newest invention called Stupidveesion, a camera that also serves as a teleporter, which will send them back to their homeworlds. When the game is nearly complete, it is revealed that Zim is responsible for this vengeful madness. Ren and Stimpy take off to Zim's ship and undo the Irken's vendetta. After beating Zim, all the Nicktoons have a party. After the credits roll, Zim announces GIR that the good guys must be prepared to face a even worthy adversary.
