How Wonderful Trophy in Yoku's Island Express
Complete Willo's quest
How to unlock How Wonderful
Willo is a character who can be found to the right of the waterfall below the village, where he'll initially ask for help in dislodging some vines - you can use the passageways to the right of this area to get your ball to the height of the flippers to allow you to do this. After this first objective, he'll ask you to return to him in the village, where he'll task you with helping him find the remaining fragments of a statue. Once all of these are assembled, you'll complete this quest and earn the trophy.
