Know Your Anenemy (Now with video yay I guess)

So, have you guys found any interesting uses for the Anenemy? Sure, you can use it as you would use a tooth trap or a bramble husk, but, at least for me, it's not worth the annoyance of having to run around it or having to kite it to get the loot.

Here's some info about the Anenemy:
- Deals 60 damage with a cooldown of 1 minute. (That's 480 per day each)
- You can realocate them with a shovel after triggering it.
- Cannot hit flying mobs such as bats (unless they are sleeping) or the dragonfly.
- Has AOE damage (cannot hit walls, which is great).
- Takes a while to deal damage after being triggered, making some mobs (such as hounds) able to get past without taking damage depending on the angle.
- Does damage even when unloaded, as long as there's a mob standing over it.

With that info I was able to come up with two uses for it:
A lazy way to gather goat milk

As you can see on the picture, there's two enclosed spots. One of the enclosed areas has the goats and the other is connected to a corridor that has eleven anenemies (enough to leave the goat low enough to die to a morning star hit). To use this you have to separate one goat from the herd, aggro it using something like an ice staff to bait it through the corridor and then give it a last hit using a morning star. (PS: Make sure to place the anenemies before the walls, I'm sure you know how the hitboxes can be a bit janky)

aaand... Another way to cheese the ancient guardian! (as if we didn't had enough of those)

If you place an anenemy under the guardian, after leaving the area it will kill the guardian in twenty-one days (obviously less if you manage to squish another one there), which is one day more than the time that it takes to recharge the atrium portal (I think it's pretty great considering you don't have to take any risks, such as losing the horn to the void). To do this you have to make it charge against you, then bait it far away enough to make it come back, record the spot in where it will stand after losing aggro on you, make it leave the spot where you want to put the anenemy and put it there, and then, finally, bait it again the same way you did to make it go back to where you put the anenemy. Sounds kinda complicated but after doing it the first time you'll see it's not (I can make a video on it if someone got confused or something).

I also tried:
> Placing one anenemy in each of the spots the mobs of the ruins would respawn after resetting the ruins, but they force dig it after respawning (kinda sad but fair). - Thanks to @Electroely info and @Bird Up picture now we know that this is possible and how to do it. Thanks guys!
> Using it to get rid of bats using a pig skin as bait, but the flying hitbox remains the same even during the "going down to eat" animation (which is a bit lame).

I guess that's all I had to share. What do you guys like to use the anenemy for?
