Snapper (Majora's Mask)
It's a Snapper! The way these
Snappers are giant turtles found in Majora's Mask. They are only vulnerable underneath their shell, so they will try to use their whole body to their advantage. They charge at enemies by retreating into their shell and then spinning across the ground. Link must try to keep his view towards the center of the room when fighting more than one so he can see them all coming towards him.
Since the goal is to hit underneath their belly, Link has to flip them first. To do so, he can use a Goron Stomp or Bombs. Another option is to turn into a Deku Scrub and jump out of a Deku Flower while they are over top of it to hit their belly directly.
