Pinstripe Potoroo is a mutant potoroo who became Cortex's minion. In Crunch's early life, Crunch met Pinstripe. After a few years or so, Cortex sends the Potoroo Gang and Pinstripe returns with his minions. Pinstripe failed and he was sick of working for Neo Cortex and he left with his minions in their flying car.
Pinstripe was on his own side with Tiny and Dingodile. Tawna dumped Crash for Pinstripe, but later, Crash forgave Tawna for dumping him for Pinstripe.
