Hey, could you do me a favor?
Well, you should have suddenly felt that it is too valuable. Then, that's OK. Please bring me one when you have enough.
Quest steps

Pet Manager Waters asks you to find him a trident.
Collect: Trident × 1

Waters cannot send the trident because of the monster eyes lurking near the village. Hunt the monster eyes for him. Monsters to Hunt - Plains of Dion: Monster Eye Destroyers, Dion Hills: Monster Eye Gazers
Collect: Map Piece × 30

You've defeated 30 monster eyes. Return to Pet Manager Waters.

The monster eyes had a map containing their attack plans! Show it to Sophya.

Sophya thanks you for the information and asks you to thank Waters for her, too. Return to Pet Manager Waters.
Nothing to kill: the quest is handed in at an NPC.
