Runaway cow

After being rescued from the slavers, Bell, due to being a sleepwalker, may sometimes randomly run away.

When this happens, she may be found in one of the following locations:
 * Forest Park — nearly the point where Rinny was trapped, being trapped herself. Lust Doll may free her right away — or "punish" her with some tickle torture or spanking.
 * Transylvania — on the streets, surrounded by succubi. Lust Doll is free to save her right away... or join the fun, and then save her.
 * New Ark City — in Police Station's prison. Lacks any scenes, but is the shortest to deal with.

Giving her Cowbell Collar would prevent her from running away again. Gifting her any other neck-slot clothes piece would make her return Cowbell Collar, enabling this quest again.
