You are either brave or desperate enough to make your way trough the zubat infested Mt. Moon.

Either way this is your current objective: travel through Mt. Moon to get to Cerulean City

You were at least smart enough to read up on the resting times of Zubat as they are neetly slumbering above you while hanging from the ceiling of the cave system. One false sound will alert them and zubat usually inspect disturbances in large groups.

Good luck!
