Trivia

 * This is the first dungeon to have TM Dig.
 * To the north of the entrance of TT, there used to be a secret shortcut directly into Tanren without needing to complete TT. That shortcut has been closed.
 * After completing TT, you may reenter it through the shortcut path using CUT instead of crossing through the maze of water bridges again.
 * Once you have beaten TT, a nearby cave will be accessible for you to pass through to reenter Tanren again. This way you will not have to complete Tanren Tunnel again.
 * Even with the HM Fly if one has not beaten TT, they will not be able to descend the hill with the updraft.
