This is the first multiplayer quest in the Patapon 3 Multiplayer Demo. It's possible to complete alone, but it's better to have other players help you, especially if you use a Yumiyacha. The mission starts in a birch forest. Move forward until you come to some bushes filled with Bonedeth. Destroy them and keep moving, but be aware that more Bonedeth squads (consisting of Tatedeths, Yarideths, and Yumideths) can spawn from the fortress up ahead. A large Cyclops will block your path, but it shouldn't be too much of a problem unless you're hit by a lot of the boulders that it throws. Once destroyed, the Cyclops either drops a Treasure Chest or some Ka-ching. Collect it and keep moving.
