The Time McChine is a time travelling device created by Viceroy. McFist ordered its creation so he could travel back to the 70s and get his favorite childhood cereal, Atomic Cavity Sugar Blasters, which has been discontinued. It made an appearance in "Randy Cunningham: 13th Century Ninja" where Randy and Howard accidentally travelled back to the year 1213 with it.
Its appearance is similar to that of a portable public toilet with some small differences. It has levers on the inside with which the user sets the desired year. It is fueled by Hardtogetium (a parody on a fictional material called unobtainium). It is one of Viceroy's few inventions that don't transform into ninja destroying robots.
