Hiploop

The Hiploop (ヒップループ, Hipuruupu) is a large, aggressive, insect-like enemy encountered in Majora's Mask. Once they spot Link, they will charge at him and attempt to knock him off of platforms or walkways. To defeat these enemies, Link must use his shield to defend against their charge attack. This will knock them backwards, allowing Link to counterattack.

Some of the Hiploops encountered wear an iron mask on their head (similar to the Helmasaur, Iron Mask, or Stag Beetle), as pictured below. To defeat these Hiploops, Link must first remove the mask using the hookshot before being able to attack it in the usual manner.
