Wario Land 3: Part 16: The Pool of Rain (Red Chest)

Description :

This level is affected by the Magic Seeds from The Big Bridge's Gray Chest. Use the vines left of the starting point to climb to the treetops, ignoring the nearby doorway that contains the Red Chest; you need the Red Key located across the top of the trees. If playing on an emulator, the beanstalk may not allow transition to the top—reset the game and try again. The Pool of Rain's Red Chest contains a Blue Skull Ring; combine it with the Red Skull Ring to unlock the new level, The Tower of Revival, on the south side of the map.
