Splodyhead, A.K.A. Experiment 619 and Splody, is an illegal genetic experiment created by Jumba Jookiba. He is designed to attack using fiery plasma blasts from his nozzle-like nose. His one true place is lighting tiki torches at the luau. Originally from Lilo & Stitch, Splodyhead appeared in the alternative version of the 2011 film Hugo, where he, along with Yaarp and Slugger, is one of Hugo's three experiment pets.
Out of all the six experiments that appear in the alternative version of the film, Splodyhead has the largest role, mainly due to being accused of killing Hugo's father, which he didn't do on purpose.
