Pixie's Lair

A secret room in the Catacombs. Pixie sometimes uses it as her hideout.

Accessing the lair
The lair becomes accessible after Rinny gets abducted during Manor quest, through one of the two secret entrances:
 * Secret entrance in the tombstone on the Graveyard. It's possible to discover it before abduction, but Rinny wouldn't allow to use it. She wouldn't have any problems with it on subsequent visits, now knowing what it's not a real tombstone. It also acts as the only exit from the lair.
 * A trapped coffin in the Catacombs. When opened, it releases magic hands, which would try to grab Lust Doll and Rinny (if present). It's possible to activate it before abduction, but you wouldn't be dragged inside. If visited at any point after abduction, you would be dragged all the way inside.

Scenes
You can ask Pixie to "feed her pets"; if you were dragged inside on the first visit, you would be forced to do it, before Pixie would be convinced what you're not an enemy. Two scenes are available (with variants if activated with Rinny):
 * Eldritch Gloryhole (requires a dick)
 * Tentacle Worms

It's also possible to skip the scenes, but lust would be reset anyway, implying what something still happens offscreen.

Trapped cowgirl
After you renovate the Milk Farm's side room, Pixie somehow captures a cowgirl and locks her up in a cell, to spoil her pets (apparently cowgirls are a different flavor). The cowgirl, of course, doesn't know that she isn't going to be literally eaten alive, so she screams for help. Pixie reluctantly accepts for you to feed the pets in her place, and after the cowgirl see you do it, she kind of warms up to the idea of doing it herself.

She is then taken to the farm and can be found sitting at the top-most table in the side room.
