Bowser's Tunnel is the second overworld of SM64: Last Impact. It is a giant chasm with lava at the bottom that Mario must avoid. It is available after 20 stars have been collected, at which point the boulders blocking the tunnel are removed. The path to the Abandoned Village is available after collecting the key from Bowser's Fiery Castle.
