Moldorm

Nothing but the sword works on Moldorm, and the sword only does damage at the tip of its tail. Hit any other part and you get knocked back, usually into a hole. Even practised players struggle with it, but the dash attack makes it easy. While dashing, the sword goes straight through Moldorm's body without bouncing off, so just running around will beat it. Only take care not to run yourself into a hole.

A giant Mini-Moldorm. Unlike the small ones, the sword bounces off it; its armour is harder than a Stalin tank. It is fast too, so you get pushed out at the edge of the ring and have to start over. Its weak spot is the tail?

A big Mini-Moldorm. Cut it with the sword and all you get is a loud clang; you cannot hurt it easily. It is fast too, so get careless and it shoves you out at the edge of the ring. Falling into the hole in the middle is very sad. Only the tip of its tail, which is shaped differently, makes a different sound when cut. Spin Attack again and again and try to finish it fast.
