Yaarp is a small, blue, lemur-like experiment with Drowsy-like ears, but with darker tips instead of stripes, four arms and a megaphone-like antennae on his head. Designed to make a literally deafening sonic blast. After Pleakley captured him because Stitch could not, he named him with a word from his native planet. His one true place as an alien invasion alarm and a buzzer for the Hula School. He is voiced by Alyson Stoner.
