Indie Super Mario Title
Press the Buttons has a post about an independently created Mario game which combines elements of Super Mario World and Super Mario Sunshine to create a great 2D gaming experience. From the post: "Equipped with the FLUDD water pack, Mario must collect pieces of a warp pipe, assemble them, and then exterminate the Piranha Plant living inside. FLUDD functions as both a jetpack and a weapon, and when the water supply runs dry Mario must get a refill at the local water hole."
I think the fact that this game came out in 2003 means that Nintendo's not going to be siccing any lawyers on the developers just yet.
