Imp's BIG Game is a game developed by Namcom that serves as a spin off to the Skip and Sqak Series. It is the first game Imp serves as the Main Protagonist. It is developed for the PS2, Gamecube and Xbox and released in October 10, 2004 in NA, November 25, 2004 in Europe, and January 14, 2005 in JP.
This game is considered to be slight darker and scarier unlike other games in the series.
The game involves Imp trying to be a hero in his friends dreams literally as he travels with the Dream Machine Dr. Tron built for him. The game is a 3D environment with set areas Imp can travel around each Dream World. The enemies you fight in the game are ghost creatures called "Nightmare Ghoulies" rather than Red Ants.
To defeat Nightmare Ghoulies, Imp has to shine his flashlight at them and suck them up with the Ghoul Sucker 9000 Dr. Tron also made for him. Each Ghost has their ability and each you can do a strategy to defeat them.
Imp isn't the only one playable, Croco and Tubby are also playable characters helping Imp by opening passages. Croco has to sneak passed Nightmare Ghoulies (since he is very afraid of them) and Tubby's stomach alerts all the ghosts in the area so you have to run away from them.
One night, Imp gets scared of the thunder storm going on outside and Dib makes fun of him. Ashamed, Imp walks away and discusses his problem with his girlfriend, Selena. Selena tells Imp that he needs to believe in himself to conqure his fears. Taking Selena's advice, Imp goes to Dr. Tron to ask if he can help him show his friends he can be a hero.
Tron builds the Dream Travel Machine, a device that looks like a washing machine, to go into his sleeping friends dreams where they each struggle problems. Imp goes into the Dream Travel Machine and goes into his friends dreams so he can show his bravory. In each Dream World, Imp encounters Ghosts called "Nightmare Ghoulies" who love scaring people.
After helping each Dream World, Imp goes back to the Real World where he and Tron relize the thunder storm caused a blackout in the Palace, and the Nightmare Ghoulies are running amuck trying to scare Imp's friends. After Imp saves his friends from the Ghoulies, a Giant Ghoulie attacks the gang but Imp defeats it. Seeing how brave he was, the team give a cheer for Imp as Selena kisses him on the cheek.
