The pcs find a hot springs pond and Gregor puts his hand in the water. Two giant frog attack Gregor and one used its tongue to grab him and drag him into the the deep water. The frog that stayed near the shore was quickly killed but the other frog was difficult to target in the deep steamy water. Just as Gregor at the water closed over Gregor's head the frog was slain.
