Megahammer is one of Bowser Jr.'s robots appearing in Super Mario Galaxy 2. This robot can be found in Bowser Jr.'s Fearsome Fleet, a location at the end of World 3. Bowser Jr.'s pod grows a mask and attaches itself to a robot body. This battle requires use of Yoshi. There are Yoshi eggs spawns around the ring. Megahammer releases Bullet Bills and Banzai Bills.

Battle

When Mario starts the battle, he must gather Yoshi who can use his tongue to grab a Bullet Bill that can shoot at Megahammer's blue glass-like orbs to break it as an attack. Afterwards, Yoshi must gather a Bullet Bill with its tongue and shoot it at Megahammer. If not shot on an orb, it won't affect Megahammer. Sling Stars occasionally appear for Mario and Yoshi to shoot at the back of Megahammer instead of walking for a long time to reach the back.

When Mario and Yoshi successfully attack all of Megahammer's blue glassy orbs, Megahammer turns its head with glass on it so Mario can use Yoshi to get a Bullet Bill to shoot the glassy part twice to fully defeat Megahammer and to move onto World 4.
