Nicktoons: Battle for Volcano Island is the first sequel to the 2005 video game Nicktoons Unite! Players assume the role of up to six playable characters from Danny Phantom, SpongeBob SquarePants, and The Fairly OddParents. The plot involves Danny Phantom, SpongeBob SquarePants, Timmy Turner (with Cosmo and Wanda), Patrick Star, Sam Manson, and Sandy Cheeks to protect the island from an all-new villain named Mawgu. Tucker Foley, Squidward Tentacles, and Jimmy Neutron also appear, but only as support and are non-playable.
It was followed by Nicktoons: Attack of the Toybots a year later.
On a distant dimension, three abnormally large crabs perform a ritual of "The Nine" saying that they will come on that day to stop The Mawgu. But Mawgu stops the ritual, scattering the heroes. Danny and SpongeBob falls from the sky with The Wise Old Crab, and The Crab explains that their enemy, The Mawgu, has escaped from his prison and created a terrible ooze which corrupts everything it touches. But the prophecies say that The Chosen Ones will save them. The Crab trains them and tells the heroes to follow him so that he can direct them to camp. The heroes stop various enemies, and then find Patrick.
They then go Shipwreck Cliff and rescue Tucker from repeatedly regurgitating penguins.
Then they are given the mission to find "The Three-Headed Boy" (Timmy). They find Timmy and stop giant, grouchy crabs. Timmy has a Jimmy communicator (which he got since many random things were falling from the sky), but doesn't have batteries. They are then sent to destroy The Great Carapace, a giant sand monster with a wooden shell. They destroy the shell and push the monster into the waterfall by using catapults. They are then rewarded with a jewel, which was the battery for the communicator. They talk to Jimmy, and Jimmy explains that Mawgu is using a Rip in Time and Space to steal energy from all the worlds and keep it all for himself. Then Jimmy sends Tucker plans for the Neutronic Rip-Zipper. It recovers all the energy Mawgu stole and closes the Rip. The parts they need for the device are scattered across the Island. After the Nicktoons gain all three Rip-Zipper pieces, they go in the Volcano, and find The Mawgu, which transports them between Time and Space. Danny and SpongeBob use blasters to push Mawgu in the direction to where the Rip is, then Tucker blasts the Rip- Zipper on Mawgu, sealing the Rip with him inside. Then, the heroes all go home, with a wall of their faces shown behind them to commemerate their victory.
