Cheese Quest 3D: The Brother Lady Saga (2005)

Cheesequest features Cheese playing a game in his head. It begins with Cheese saying he likes games and sticking a video game cartridge into his mouth. He then goes into his imagination, avoiding obstacles, completing a monkey dance lesson, getting a horsey, fighting a boss (cake), getting a "Water Horsey (a shark that Cheese rides)", and avoiding falling cereal. After he avoids the cereal, he says "I like- CEREAL!" and he takes the video game out of his mouth.
