Yaarp, A.K.A. Experiment 613, is an illegal genetic experiment created by Jumba Jookiba. He is designed to create devastating sonic blasts from his megaphone-like antenna. His one true place is at Lilo's hula school as an alien invasion alarm and buzzer. Originally from Lilo & Stitch, Yaarp appeared in the alternative version of the 2011 film Hugo, where he, along with Slugger and Splodyhead, is one of Hugo's three experiment pets.
