When performing the Hammer Drop, Mighty jumps into the air, where he curls into a spinball. He then drops directly downward with a burst of speed so great that he leaves afterimages and the air spirals around him. Upon impacting the ground, he will then deal damage.
In gameplay, the Hammer Drop is a maneuver that not only deals damage to Badniks, but can also pierce through them, and can even take out the Beanstalks' heads. The resulting shockwave from hitting the ground will also take out Badniks and traps (like the landmines in Flying Battery Zone) close to Mighty, as well as making hidden Item Boxes fall from trees. The player can even use this move to destroy the Frozen Spikes in Press Garden Zone (though doing so will force Mighty out of his ball form), and clear out holes in the terrain, allowing access to new routes. The move also lets Mighty pass through certain breakable elements without bouncing off of them (such as the lids covering high-speed warp tubes in Chemical Plant Zone) and shoot straight through the funnels in Studiopolis Zone.
- The Hammer Drop is similar to the Bound Jump.
- In the internal files of the PC version of the game, the Hammer Drop is instead referred to as the "Drill Dive".
