PJ, A.K.A. Experiment 133, is an illegal genetic experiment created by Jumba Jookiba. He is designed to play practical jokes on unsuspecting victims, hence his name P(ractical) J(oker). His one true place is performing an opening act for Moses' hula gig. He is voiced by Jeff Bennett.
He was activated when a fat guy threw his pod into the ocean. In the group photo taken at the end of Leroy & Stitch, PJ is not wearing his glasses.
PJ is an orange and tan koala-like experiment with a white face and white belly, a wide mouth, red nose, black eyes, two thin yellow-tipped antennae on his head resembling rabbit-like ears, and a functioning blow-horn for a tail (reminiscent of Harpo Marx's trademark horn), which he squeaks instead of speaking. He wears joke eyeglasses with a fake nose and mustache resembling those of Groucho Marx.
PJ is a skilled practical joker. He can play practical jokes by using his surroundings as well as other things he finds.
PJ has shown to be skilled in playing the trumpet.
