Knuckle Mushroom

The Knuckle Mushroom is a power-up in the Mario franchise, first appearing in New Super Mario Bros. 3. When touched, Mario will transform into Knuckle Mario.

The Power
When Mario gets this mushroom, he becomes Knuckle Mario and his hands are twice bigger, allowing him to punch powerfully. When he has this power, he can punch, uppercut and use slide attacks to destroy enemies. Additionally, he can also run while crouching, dash across gaps and through obstacles quickly, and climb on blocks.
