This invention is originally tested on Carl by Jimmy in Crime Sheen Investigation which is cut short by Sheen asking the boys for help in finding his favorite toy. In Crouching Jimmy, Hidden Sheen however, it has a much larger role in first helping Sheen dance into Libby's heart. When this goes awry due to ninjas of Shangri-Llama kidnapping Libby on orders of the main antagonist, Yoo-Yee, Jimmy uses it to teach Sheen kung-fu so that they can return Libby back home safely.
