Wario Land 3: Part 24: The Frigid Sea (Gray Chest)

In this Music Box world, Wario freezes the ocean with a magic spell, creating a stage of icy terrain. Players must watch their footing as Wario can slip and slide, and Brrr Bears add extra challenge. The Gray Key is hidden in an upper left‑hand wall near the start; using ice platforms, players can reach the Gray Chest on the other side, noting a frozen waterfall to the right. The chest contains the Head Smash Helmet, restoring Wario's ability to smash blocks from below, effective on both cracked and solid purple blocks. The east side of the world is permanently set to night, even if entered during the day; this issue will be resolved later.
