Chasupa

The Chasupa or are flying eyeball enemies that first appeared A Link to the Past. They originally appeared in Hyrule Castle Tower, where they behaved in a similar manner to Keese. They later appear in the Dark World, first in the Thieves' Town dungeon. The ones that appear in the Dark World look identical to the ones that appear in Hyrule Castle, but are actually stronger, able to withstand more hits and cause more damage. In Four Swords Adventures they are rare enemies that will only appear in special circumstances, usually when a switch or a lever is pulled. They fly in a group of four, much like Green Zols in the same game, and if the four Links defeat them all they will obtain a large Force Gem. They will circle the area before flying away, and do not pose any real threat, and can be defeated in one hit each.

Trivia

 * Chasupa seems to be related to Patra, and may actually be the smaller eyes that usually surround Patra.
 * Chasupa are also very similar to Eyeball Monsters.
