The "Lacking Nothing" Microwave oven is one of Kururu's inventions.
It was shown in Giroro: The Man with Seven Faces de arimasu.
The microwave allows you to amplify and use your inner powers; however when Giroro used it, he split into 6 forms of himself, namely Giroppe, Girorin, Girocchi, Giro-sama, Girokko and Giropon.
The machine looks like a microwave, as indicated by its name.
There is also another part which, ironically, is shaped like a mechanical sweet potato.
