Wario Land 3: Part 85: The Warped Void (Green Chest)

Description:

After finding the Red Chest Treasure in Part 84, I revisit the level to collect the Green items. I head left from the start, go through a portal into the green section, clear enemy blocks with barrels, use portals to reach the Green Key, then find a warp portal that drops me into a tricky room leading to the Green Chest. The Green Chest contains a bottle of Demon's Blood, which is used on graves in the Forest of Fear to summon undead that Wario will seek for help.
