Tunnel is an abillity in Super Princess Peach Wii. In the abillity, Perry turns into a drill and tunnels into the ground. Under the ground, tilting the Wii Remote up causes Perry to drill up and tilting it down causes him to tilt down. However, it can only be used in areas with soft (light brown) soil. To use it, you must draw a circle on the soft soil in abillity mode.
