Angler Fish

The Angler Fish has appeared as a boss enemy in Link's Game Boy adventures. It strongly resembles its namesake.

Link's Awakening
Link encounters this boss in Angler's Tunnel, the fourth dungeon in Link's Awakening. Angler Fish is the nightmare guarding the Surf Harp. It can use a ramming attack, fling enemy fish at Link, and drop debris on him.

Link fights it under water. Its vulnerable point is the esca (the fleshy growth resembling a lure) that hangs from its forehead. Slashing rapidly with the sword is most effective, but the Bow and Bombs will work as well. This boss needs very little strategy to defeat and can be killed even before it has a chance to attack.

Angler Fry also appear during the battle. They are to the Angler Fish as Garahna are to Gyorg in Majora's Mask.

Oracle of Ages
The Angler Fish makes another appears in Oracle of Ages. Although Link encounters this mini-boss in Jabu-Jabu's Belly, the battle is fought on land. The Angler Fish will either jump on top of the young hero or spit bubbles at him.

The best strategy is to shoot it with the Seed Shooter to bring it down, then strike its esca with the sword. After taking some hits, the fish will re-puff and bounce around, shooting bubbles. After several repetitions of this pattern, the Angler Fish will explode.

Trivia
If the Angler Fish in both Zelda games are the same as real-world Anglers, then both the Anglers Link fought were females as males are small minnow-like fish without a lantern.
