Monster statistics extracted from online SRD wiki, not the published hardcover edition.

Bats are nocturnal flying mammals. The statistics presented here describe small, insectivorous bats. They have a natural sonar that allows them to operate in total darkness; for game purposes, treat this ability as Darkvision.

A group of normal-sized bats has no effective attack (at least in terms of doing damage) but can confuse those in the area, flying around apparently randomly. For every ten bats in the area, one creature can be confused; such a creature will suffer a penalty of -2 on all attack and saving throw rolls while the bats remain in the area.
