Spongebob and Danny Phantom: Battle for Volcano Island is a pretty good game.

User Rating: 7.5 | Nicktoons: Battle for Volcano Island GC
This is the kind of game you can probably beat in a day, but beat over and over again a lot. With only 10 levels, this game is pretty short. Also, only the Spongebob and Danny Phantom franchises are really represented. Timmy Turner is a playable character, but you can only use him in 2 levels (One of which is his bonus level), and Jimmy Nuetron isn't playable at all. However, this game has enjoyable game play and easy to learn controls (A is to jump, B to attack, X for a special move). The plot is somewhat corny (An evil monster named Mawgu is using a rip in time and space to steal energy to make himself more powerful), but it works. The graphics aren't the best, but that's a pretty good thing when dealing with cartoon characters. You can play as 6 characters, Danny Phantom, Sam Manson, Spongebob Squarepants, Patrick Star, Sandy Cheeks, and Timmy Turner. However, when you begin a level, you can't choose what 4 characters you're taking with you, which kind of stinks. Also, you can unlock bonus levels by locating salvage items across the island. Don't be fooled, as these "bonus levels" are just you using a specific character to race against the clock to the finish line at the end of the level. Overall, the pros exceed the cons in this game, and although there are some minor flaws, it is a pretty enjoyable experience.
