Unknown Planet

Overview
Exists in an alternate dimension where Wario and co. are teleported in Chapter 5. The Old Man was stranded there by the ancient Bimsons of old a long long time ago. The Old Man is freed from the planet when he destroys it accidentally while trying to kill Wario.

It is a baren wasteland with little to no life living there. The only notable life form living there would be the Old Man until he blows it up and escapes.
