Jimmy has invented the "Metabolic Accelerator" machine, with the purpose to advance aging by accelerating one's metabolism. This device somehow looks like the Chrono Arch. Jimmy demonstrated how it worked by throwing an acorn through it, causing the acorn to instantly become an oak tree. Jimmy, Carl, and Sheen tried to use it make themselves 18 years old so they could purchase a rated M game. However, it initially seemed to have no effect on them since they strangely still looked the same following their use in it, but the next day, they found that they had grown into elderly men from it and would continue aging until they turn into dust since Jimmy did not make a strong enough time brake. Once he used the proper amount of Titanium for the time brake, he was able to return them to their own ages in the nick of time.
Looks[]
