Flying Fish

Flying Fish are sea-based enemies in The Legend of Zelda: Phantom Hourglass, resembling flight-capable. They appear in the Southwestern Sea and the Northwestern Sea, and are the most basic of the sea enemies other than the passive Squiddy. They only appear once the cannon is obtained, which can defeat them in one hit. They burst from the water and follow along in front of the ship, eventually charging into it if left alone.

In The Legend of Zelda: Spirit Tracks, Snurgles have their basic function.

Trivia

 * Flying Fish may have had a resemblance to Keese earlier in development, as it is known as SeaKeeth in the game files ("Keeth" being a romanization of Keese used in the game's files).
