Oh, just know that this nature or survival check will require you to closely inspect the crystal, this could be done by going to them or asking Your High Priest to get one of them close to you. No jump scare, I promise.
Are they all just regular kuo-toa or are there any whips or monitors among them?
Also, I notice that you refer to Blibdoolpoolp as a high priest rather than an archpriest. Does that mean he has something other than the kuo-toa archpriest stat block?
Hey, I'll say that there are 5 Whip Kuo-toas, including the high priest, but the high priest also has one level 2 spell slot and knows Lesser Restoration. And 2 Monitors.
