Over the Hedge: Hammy Goes Nuts is a video game released for the Game Boy Advance, Nintendo DS, and PlayStation Portable. The gameplay varies based on certain versions.
Hammy is watching television when it goes out. Hammy freaks outs and Verne comes over to see what is wrong. It is revealed the satellite that it is hooked up to is being fixed. RJ leads a mission where the three try to rewire the dish. In the middle of the mission, they find a beaver named Boris locked in a cage. After freeing him, he agrees to help Hammy get the television working again for the price of helping him gather supplies for a dam.
After gathering enough supplies, Boris reveals his true colors by leaving the animals and building his dam. After the animals notice the flooding, they travel to the dam to put a stop to Boris' plan. Hammy defeats Boris and saves the forest. Boris then leaves a note, saying he has gone to a different city to build a smaller, much more stable dam.
The GBA version is a mini golf game. Its story line is a bit different from the PSP version.
The PSP version is a platformer, much to the likes of Over the Hedge: The Video Game. Unlike the GBA version, there is more content.
