Sparky, A.K.A. Experiment 221, is an illegal genetic experiment created by Jumba Jookiba. He is designed to create crippling electrical surges. His one true place is powering the Kilauea Lighthouse, which had been abandoned for requiring too much electricity. Originally from Lilo & Stitch, Sparky appeared in the alternative version of the 2011 film Hugo, where he, along with Slushy and Richter, is one of Isabelle's three experiment pets.
