|“||Smash the ground with the Grand Hammer! Shake the Wii Remote to power it up, and pound even huge stakes flat!”|
|— Grand Hammer's Flavor Text • Kirby's Return to Dream Land|
Grand Hammer is a Super Ability that appears in Kirby's Return to Dream Land. This ability is an upgraded version of Hammer, and is acquired by inhaling a Super Bonkers after it has been defeated or by inhaling a giant white hammer (only during the battle against Magolor EX).
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.
