I picked Robo Mario because I like the idea of a Mario doppelganger who is also a robot, similar to Metal Sonic. Too bad Robo Mario only appeared in the Mario Kart Arcade GP games, because I thought it would be a fantastic addition to the Mario roster, as opposed to Metal Mario (who is basically Mario with a metallic skin.

Thank you for reading.

Definitely the time machine from Partners in Time, because that's the one I wish I had.

The Virtual Boo. It's the new map and such. Basically the Dual Scream but with the map having red outlines (like the Virtual Boy). It has a hotline to E. Gadd for hints. I chose other for this, since I love having hints. :P

I picked Robo Mario but maybe I'm just biased.
