Pinto Rappa (ピント・ラッパ Pinto Rappa) is a character that only appears in the anime series. She is Parappa's younger sister. In most of her appearances, she is followed by a lunch box monster named Uee (ーイー Uī). This is similar to the way that Boxy Boy is seen as a companion to her brother.
- A running gag in the series is when Pinto goes to PaRappa's room to tell him something, she always tells him someone's on the phone to him.
