Where it is

From the official guides

A blood-sucking bat that likes to live in dark places. It usually clings to walls, but flies at Link when he comes close. The boomerang from a distance works well.

A bat that lives in the waterways underground, and in caves too. The boomerang can beat it, so keep throwing the boomerang as you go.
