They will drink if you give them booze in a mug, they'll also... err... consume
anything you give them in a mug, even if it's a cage which they're somehow inside of.
Gobbos don't have pantheons normally, their gods are big scaly lizard bastards and huge eyeless porcupines that spit webs and live in their slade spires (unless someone drops it on them, heh) so no luck there. Their site layouts don't really support normal zones like that anyways, if you have a library at one it's just a ton of books in one of the troll pits with scholars biting each other to death, and I've yet to actually find the taverns that are supposedly present at a few that I've checked top to bottom, so there's no reason to expect a temple to show up as a big engraved block of stone somewhere.
If it was conquered by another civ which builds temples and libraries, THEN you could find one, I've seen human town style temples in forest retreats along with their enclosed library buildings after they had been ruling a forest retreat long enough in world-gen.
Also, I added huntsman spiders as a subterranean pet that hunts vermin like cats and whatnot, galloping around being goofy in dwarven sites right?
...for some reason that amuses the hell out of me.
"Oh shit, it's a yeti, look out!"
'I hope it doesn't eat anyone.'
"Nah, I think this one is brain-damaged."
'For a yeti? How could you tell?'
"It just ate a gigantic spider."
'Ah, definitely dropped as a yetibaby then.'
