Yaarp, also known as Experiment 613, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to create devastating sonic blasts that can shatter windows, flatten buildings, and cause acute loss of hearing. Luckily, he can also reduce these noises to soft, gentle honks. His one true place is at Lilo's hula school as an alien invasion alarm and buzzer.
