The Cave Zone (sometimes called the Bat Zone) is the fifth zone in Frogger: He's Back! and the first unlockable zone in the game. This zone, like the Machinery Zone, has only three levels in it, the final level of this zone having a Gold Frog in it. The main enemies here are spiders and bats. This zone is also unique for having flies that light up the zone a for a few seconds. Croaking will also light up the zone for a second or two.
