Play The Fairly Oddparents - Shadow Showdown (u)(rising Sun) Online

I picked up The Fairly OddParents: Shadow Showdown for the Game Boy Advance back in 2004. It was published by THQ, a familiar name for licensed games on that system. This was the sequel to Breakin' Da Rules, and it fit right in with the other platformers and cartoon adaptations that filled the GBA library at the time.

You control Timmy Turner, navigating through side scrolling levels based on locations from the show. The main goal is to stop the evil Dark Laser by fighting through his shadowy minions. You have a basic punch attack, but the real fun comes from using Cosmo and Wanda's magic. You can transform into different forms, like the Big Strong Man to break certain blocks, or turn into a bowling ball to roll through enemies. You also collect these little gold trophy icons to unlock new areas. The pacing is pretty brisk, and some of the later platforming sections can get tricky with their timing. It feels like a straightforward, energetic run and jump game from that era.
