Volcanic Tunnel (パドントンネル Padonton'neru?, lit. "Padon Tunnel") is the second level in Tails Adventure for the Sega Game Gear, coming after Poloy Forest and before Polly Mountain. Though thanks to the non-linear nature of Tails Adventure, the young fox must return to the region on various occasions as new items (specifically, the Triple Bomb) open up new routes.
