Lady Bug (Arcade)
This game has unused graphics.
Lady Bug is a Pac-Man-like game with an insect theme, flipping gates, and many more opportunities for bonus points. Plus, it's one of those rare Arcade games (along with Mr. Do!) where you can actually earn a free game!
He's much too large to fit in the maze or in the side areas. Why he's here, and what purpose he would have served, is completely up to speculation.
