in the large open area, the one that has a lot of water and wooden plank pathways and one moving magnet... there's a treasure chest at the very northwest corner of this area, exactly above the same place where you can find fairies in pots. this chest appears to be on some very high up platforms. i dont know how to get up there! ive tried dropping onto one of the platforms from the moving magnet, ive tried using my boomerang on two torches on the highest platform, and ive tried plain old jumping. how can i get this treasure chest?
