#power up-s

It's probably/definitely been made as a thread before, but what new power-up ideas would you add to Mario games? Personally would like to see a classic mushroom in a NSMB game for Mario to have his moveset and physics from the original SMB1

Ok so the player (you) is in a impossible level (anything will kill the player). The only things you got are a Fire Flower, Super Star, Super Leaf, and a crafting table. How would you get pass the level?
