Make a Slime & Octopus Omok Set

It seems Casey in Henesys Park can make another type of Omok Set.

Casey, whom I met in Henesys Park, said he could make a new type of Omok Set, and asked me to collect a few items. He said I could get them by defeating Stump, Slime, and Octopus found around map and map. I should try to gather them when I have the time.

I brought the requested items to Casey in Henesys Park and received a Slime & Octopus Omok Set! With this, I can play the Omok mini-game with other adventurers anywhere! I should remember to ask Casey if I want to know more about the mini-game.
