RESOURCE REQUEST: SUPER MARIO TILES & CHARS

Hello everyone,

I want to create a dungeon in my RPG, which has the look and feel
of Super Mario.

Something in that kind:

I am also looking for (RPG Maker XP) Character Sets of Mario, Luigi, Toad and some enemies: Red Koopa, Green Koopa, the funny magician, who has always annoyed you :)

I would be glad for any sprite or location, where I can download them. (Free for non commercial use resources, credits given to the author)

Thanks in advance :)
