'Im-a the Master, okay?'

Super Mario...the Royal Knight of Mushroom Castle.

I've been meaning to do this for a long time.

As far as gameplay mechanics for Mushroom Kingdom Hearts, i really wanted a recruit process on this game (I know almost everybody that played Kingdom Hearts 2 wanted to take Auron everywhere they went) The recruitment side-quests would vary depending on who you want to obtain and each character has their own "Relationship Level" that boosts depending on doing favors for them, saving their world, bringing other characters together in various guilds, etc. (Think Radiata stories)...Mario would probably be the last (if not best) character to summon by your side.
