While Emagor doesn't find anything of particular interest inside the frog, unless he is interested in the physiology of the beast, he does notice the pendant, that the frog 'wears' like a necklace. The small piece of jewelry is shaped like a pyramid - like the pyramid they can see on the small island in the Barren River.
Kordunn had told them, that they found a similar pendant earlier, when they fought another of these predators near Sokol Keep, and that it seems to allow its owner limited control over the creature and the ability to see anything in its vincinity.
