His last known whereabouts: the sky. The Moon is Earth's closest neighbor. For centuries, people worship the Moon as a goddess and it is powerful.

For over four billion years, the Moon has circled the Earth more than 27.3 days until today when Robocrook snatched our nearby satellite and left a big space in space. How could he do such a thing? Maybe he just took a shine to it. Gumshoes, its your job to stop...

(singing) Woo-woo-ooo-oo
