This is BigOto2's 10th custom track, created with the CTools BRRES creator. It features two caves; one big one filled with water and gigantic pipes, and one small volcanic one filled with lava. The track took about six weeks of on-and-off development. It was originally going to be called "35000 Feet Under", but due to a name suggestion by WorldsBoss (who also originally inspired the author into making this track), the name was changed.
