The Fairly OddParents!: Shadow Showdown is a 3D platformer game based on The Fairly OddParents cartoon. When the TV goes out just as the season finale of Crash Nebula starts, Timmy Turner asks his Fairy Godparents for a little help. When they find their magic is gone, they travel to the Fairy world, where they quickly learn that the Royal jewel is missing and Jorgen von Strangle thinks a recently fired jester is responsible. Now the player is off to uncover the truth.
Players take control of Timmy Turner and guide him through a variety of environments ranging from Fairy world to his dad's dream world. Gameplay includes mostly platforming and a bit of puzzle-solving. As well as collecting wish stars (3 stars for a wish) that let the player obtain items to overcome obstacles like a pogo stick, glider or jetpack.
