The Super Hammer, rarely appearing around rocky areas is used primarily for construction, but it's a good power-up for adventures, too. The user gets a nice builder suit with a hard hat (because safety first), and it comes with a hammer too which can smash regular brick blocks to tough hard blocks which may reveal secrets when lucky. The user can also summon boxes that they can toss around, which is also nice because it floats on water, and despite being wood, lava too. Probably a good power-up to have if you still believe you hit the blocks with your head rather than your hand.
