Giant Catfish

The is a character in A Link to the Past who has made his home inside the circle of rocks in Lake of Ill Omen, in the Dark World.

Near the ring where the Catfish dwells, there is a sign that says: "Curses to anyone who throws something into my circle of stones." If Link ignores the sign and follows the advice of the bird-like creature in a cave south of the Palace of Darkness by throwing a skull, a bush, or the sign itself into the circle of stones, the Giant Catfish, who was having a nap, appears and gives him the Quake Medallion in return for leaving it alone.

After that, disturbing it by throwing another item into the ring of stones causes the Catfish to spit a fireball or throw a Bomb out.
