Quest 95

Speak to Fuffupu in the town of Orphea to begin this quest. He's located at F4, in a house near the church. He needs your assistance in order to repair the town's famous Big Horn. In order to do this, you'll need to get Pom Pom Oil (ポムポムオイル) which drops from Discombombulators (ポムポムボム) in the Underground Lake Cave (地底湖の洞くつ) on the Wena Islands.

Upon arriving at the Underground Lake Cave, seek out the Discombombulators towards the back of the cave.

Defeat them until you receive the Pom Pom Oils, and then return to Orphea Town. Head to the Big Horn at G5, interact with it twice, and then receive your reward from Fuffupu.
