Wario Land 3: Part 73: The East Crater (Gray Chest)

This volcano already had a West Crater, so why not an East one? Going downwards in this level can be a hassle at times, because it tends to be packed with those Pneumos enemies that can send Wario back up by turning him Puffy. You'll also have to keep grabbing barrels to clear the way of Enemy Blocks. The Gray Key is above a big gray frog. You just need to force him to be a platform towards it by shaking him upwards with a Super Ground Pound. Then, go back out the way you came and pick up Hot Wario. Get as close enough as you can to the gray frog before Wario's completely immolated and he'll have enough time to burn through both that frog and the frog in the last room that contains the Gray Chest. The East Crater's Gray Chest Treasure is... The Super Grab Glove! The final powerup to bring Wario back to his full strength! This allows him to pick up bigger enemies. They'll still be heavy enough to slow him down, but he can still throw and even super throw them! You'll need this power for more puzzles leading to more treasures.
