The story line centers on PaRappa, a young puppy, who has recently won a hundred years supply of noodles and has grown tired of eating them. PaRappa's girlfriend, Sunny Funny, offers to make him dinner one evening and he gladly accepts. However, when she serves him noodles, PaRappa throws a tantrum, leaving Sunny Funny to call him a baby. To prove to Sunny Funny that he is not immature, PaRappa seeks to complete a number of tasks, such as getting a job at a Beard Burger restaurant or working out to Chop Chop Master Onion's romantic fitness television program.
The plot continues to become more bizarre as the story ensues and it is slowly revealed that all of the food in town is being turned into noodles by a military dictator. He and his friends get shrunk by his father's invention, so he helps coach them back to normal size with the help of Guru Ant. PaRappa gets drafted into the army and must complete a military boot camp training course with Instructor Moosesha.
PaRappa confronts the inconsiderate Colonel Noodle. The Colonel turns out to be Beard Burger Master's son, who has become sick of eating burgers. PaRappa convinces him that noodles aren't the only food around. The game ends with a final party with returning hip-hop master MC King Kong Mushi, and PaRappa learns that Sunny Funny already likes him the way he is.
