Q*bert 2 (Lost Game Boy game; Date unknown; Existence unconfirmed)

Q*bert 2 (or Q*bert II) is a possibly lost Game Boy game. Very, very little is known about the game, all that is know is that it was being made for the Game Boy, and it was going to be a sequel to the 1982 arcade game Q*bert.

Clues
IGN has it listed as an unreleased GB title, and LoveROMS.net has the GB version of the original listed under this name. One guess would be that it was a working title for the game, but we may never know.
