Jr. Pac-Man (Arcade)
This game has unused graphics.
A whole bunch of unused fruit-toys. There's a skateboard, a cowboy hat (which appears twice for some reason), a rattle, a baby bottle, a pogo stick, and a pacifier.
Early (or otherwise alternate) unused graphics of the drum set and the cat, which differ slightly from the ones used in-game.
Two large circles of unknown purpose.
An unused Yum-Yum, seemingly meant for the title screen.
Part of Namco's logo is here, due to some of the game's graphics being copied directly from Pac-Man.
A leftover key graphic from Pac-Man, a "fruit" that is not present in Jr. Pac-Man.
A tiny X is used as padding in the game's graphics.
The final sprite of the cat has a thick outline around it, but it is blacked out due to the color palette used. This is what the graphic would look like with the outline enabled (colored blue).
