The father will award Cecil with the Adamantite ore if brought a Rat Tail. This can then be taken to Kokkol's house with the Mythgraven Blade and refined into the Excalibur. After bringing him the Pink Tail dropped from rare enemies known as Flan Princesses, he will give the Adamant Armor. In the 3D versions, powerful enemies such as the Red Dragon have a slim chance of dropping additional tails, which may be brought to the man at the Grotto for additional Onion equipment: In Final Fantasy IV: The After Years, the cave appears connected by land to Mythril, and is the first dungeon of the game.
