Angler Fries are fish enemies featured in Link's Awakening.
Angler Fries only appear during the battle with the boss of Angler's Tunnel, the Angler Fish. These hatchlings shouldn't cause Link any trouble. As long as he doesn't touch them, they will never attack him. All he has to do is hit these enemies with his Sword to kill them. However, Link must be aware, because their mother will never stop attacking him.
