Sneak Peak is a secret course resembling Mt. Lava Lava in Wario Land: Shake It! Its map is hidden in Mt. Lava Lava. Like Mt. Lava Lava, Sneak Peak is a volcano with pools of lava being the main impediment. Some enemies found in the level are Volcannons and Bandineros. Boulders are also found that can crush Wario, but can be used to get treasure and coins. When Wario finds the caged Merfle, he'll need to avoid boulders and Volcannons and run back to the start before time runs out.
Hidden in Sneak Peak is the map to Lowdown Depths. Wario must first reach the where a large golden Coin is found above a few metallic blocks. Pounding these blocks will cause a boulder to roll. Going far to the left side, performing an Earthshake Punch, Wario finds the map. The 'Golden Enemy' here is a Shortfuse.
