There appears to be a maximum of one eggplant of either variety in Sheepridge at any given time, however, if the eggplant is killed it can respawn later during the same night.
The eggplant spawns with the following room chat: A rogue eggplant scuttles out from a dark hole and looks around eyelessly, with a mouthless evil grin.
Once the night has ended if the eggplant is still alive it disappears with the following room chat: The rogue eggplant scuttles away into a dark hole.
These were all observed in the room "dark alley" 1 W of the town square. With further observation we may be able to determine what the respawn time is for the eggplant. --Spookee (talk) 17:32, 27 October 2022 (EDT)
