Naboo Abyss

The Naboo Abyss was a series of submerged, cavernous tunnels that ran throughout the planet Naboo, reaching the surface and passing through the world's core. A variety of creatures lived throughout the tunnels including the opee sea killer, colo claw fish, yobshrimp and sando aqua monster. The Jedi Master Qui-Gon Jinn, his padawan Obi-Wan Kenobi and the Gungan Jar Jar Binks traveled through the Abyss in a Gungan bongo submarine when attempting to reach the city of Theed from the aquatic city of Otoh Gunga.
