Super Hammer (Super Mario Maker 2)
From the Super Mario Wiki
The Super Hammer is an item appearing in Super Mario Maker 2, exclusively in the Super Mario 3D World style, unlocked after clearing the Meowser Showdown! level in Story Mode. Picking one up transforms the character into their Builder form, allowing them to use a hammer to break Hard Blocks, as well as Thwomps, and any other breakable object, and place down up to five Builder Boxes at a time, which act like Crates.
