(usually one of the mobs is a sporebat that can be hibernated) It's also very close to the entrance, and spawns in that location every time (since the old location for the alternate spawn point where you used to be able to grab it without killing any mobs was removed), for very quick in-and-out farming.

There's also a very nice supply or [Ancient Lichen], [Sanguine Hibiscus], and a few Adamantite deposits that can all be farmed without having to kill any mobs.
