Halloween Bats

This object looks like a small, lazily drifting flock of bats. When an avatar approaches within 5 metres, the bats will furiously mob them, screeching and making menacing sounds, until they retreat at least 15 metres away.

The distances are configurable by editing a notecard.

Copy-mod, so you can rez several of these in an area.

I have a gloomy churchyard on the marketplace that is an ideal location to use these.
