Digger Tunnel

The Digger Tunnels are large caves opened up by the Hag 1 digging drill while on its way to the Cauldron Keep in Banjo-Tooie. Klungo engages Banjo and Kazooie inside the each of tunnels for the first two of the three battles with him. Once the battle has been won, the tunnels cannot be reentered.

Since the tread marks from Hag 1 lead straight through the caves rather than all around inside them, it can be inferred that the caves were not created by Hag 1 and were merely tapped into.
