The player takes on the role of PaRappa, a paper-thin rapping dog, determined to procure the heart of a flower-like girl he has a crush on named Sunny Funny. However, he is intimidated by the presence of Joe Chin, a rich, self-centered dog going overboard making efforts to obtain Sunny's attention. In order to win Sunny, PaRappa learns to do karate at a dojo, and earns a driver's education course to get a license. However, when he crashes his father's vehicle, he has to earn money at a flea market to pay for this. When Sunny's birthday comes up, PaRappa has to get her a cake but ends up ruining it after an encounter with Joe Chin. He makes a new one by watching a cooking show and proceeds to eat a lot of it on the day. When spending some time alone with Sunny, he is suddenly overcome with the need to go to the bathroom and has to rap against his former teachers to get to the front of the queue. Then one night, PaRappa is invited to Club Fun, and asks Sunny to go with him, to which she agrees. PaRappa then raps on stage with everyone, rapping solo at the end of the song showing that he's showing interest in Sunny.
