Mario gets trapped in an MS Paint bag by Not-Bowser, so it's up to Luigi and Yoshi to save him. Unfortunately, the result is a lame educational game that attempts to teach geography but fails miserably.

Do we even count this as Luigi's first starring role, as opposed to co-star? We do? Dammit.

Unused Graphics

Present in the graphics of the main hub castle is a rectangle with a red dot. Purpose unknown.

Sprites of Luigi in the world map, Yoshi sticking his tongue out, and alternative sprites of Luigi riding Yoshi go unused.

Bowser has two unused facial expressions.

A smaller version of the key.

An alternative sprite of Koopa, and his shell along with him sliding and world map sprites of him facing forward and backwards. In the final game, if you stomp on Koopa, he just explodes.

Pokey. He never appears in the final game.

An alternative sprite for one of the NPCs.

Alternative sprites for mario (look at his shoes). Also unused sprites for the ending.

An unused building that is supposed to be part of the map.

Unused and alternative big graphics of the tools. The clock and key are never used and the computer is an alternative version of the one used.

Unused letters for the Radical datafax.

Various unused tiles.

Mario shoes are supposed to be brown like normal but it can't be seen.

The computer is supposed to have a brown outline around the monitor.
