Feyesh

A Feyesh (, Patch) is an enemy in Super Smash Bros. Brawl's Subspace Emissary mode and first appears in the Sea of Clouds level. It appears like a flying, slightly fish-like creature with a giant cyclops eye and five tentacles. It attacks with electric stings from its tentacles. The damage and knockback accrued depends on the difficulty level and the number of tentacles that hit. It can fly normally, but when it spots a player character, it dashes towards it. Ironically, a Feyesh will vanish into bubbles if it touches water in any SSE stage.

Name origin
Feyesh's name is the word fish with the word eye included in place of the letter i, a reference to how eye is pronounced like said vowel and being that the fish have a very large, single eye.

Trivia

 * The Feyesh looks similar to the Mogall and Arch Mogall enemies from the Fire Emblem series, The Legend of Zelda enemy Patra, and the Monoeye from the Kid Icarus series, as all three somewhat hover and are mostly made up of a single eye.
