Although Grand Hammer's attacks are heavy and unwieldy, like Ultra Sword and Monster Flame, every other character besides Grand Hammer Kirby pauses during the attack, so it is impossible to miss anything beneath Kirby, which is a good thing as the ability only pounds objects into the ground if he is directly over it, regardless of how large the size of the hammer's head may be. The first size pounds in a third of a large stake, the second size pounds in two thirds, and the third will pound in an entire large stake.
Kirby enlarges his hammer and performs a powerful overhead swing, smashing it on the ground beneath him, generating a shock wave. Moves objects down one unit.
