Indeed the items these drop is incorrect. Thanks for posting the correct info, HS. I've EXP'd on 3 tiers of Snolls over many levels and I can verify the drops that HS has mentioned are in fact the correct drops.
Also, if you're playing BST, it's a wise idea to carry at least 2x Yagudo Drinks on you when killing any of the Snoll family. When you're pet swaping, you'll get hit with Cold Wave a few times and this skill is no joke as the freeze DoT is vicious. It will take around 700HP at 10-15HP per tick and that's on the lower level Snolls. I've no idea what Cold Wave from the next few tiers of Snolls will tick at, but my guess it's for more and it will last longer. If you don't have enough MP to heal yourself, then you're going to die a slow death. Best to carry a couple of Yagudo Drinks with you to ensure you have enough MP to Cure yourself. If you have Erase, then you can simply remove the ailment it with Erase.
