PaRappa attempts to reconcile two different promises he made with two different friends. First, he tells his buddy PJ and PJ's friend Matt that he'll play basketball with them on this particular day, but also tells Katy and Sunny that he'll go with them to Sister Cone's garage sale. Things get worse when Paula shows up and angers Katy by questioning her fashion sense. Gaster also further ruins PaRappa's day by stealing his bike and the money from the garage sale.

PaRappa is worried by an ominous car following him and his friends, but it turns out to be MC King Kong Mushi wanting to hire PJ under his record company. Mushi watches PJ live and is impressed by the performance and PJ is signed up... However, things take a downward turn.
