A gigantic frog made of living crystal. Clearly from another plane, it currently lives in a subterranean lake in the Saurian Wasteland.

In order to appease the creature, Saurian priests offer sacrifices of dead citizens. They are dropped from Dunshab Lakebed above into the lake below. Assuming incorrectly, the frog is not interested in devouring the bodies it is fed. Instead, it is drawn to the treasures that arrive with the bodies.

Inside the beast’s mouth is like the center of a geode: crystal structures grow all around, slowly enveloping and dissolving the treasures this beast has consumed.

It closes its mouth, crushing you against the rough walls of its throat, then spits you back to shore. - Saurian Wasteland (GS-ADV5)

Decades ago, Khalo Zat was successful in opening a portal into Kleetoth, Plane of Crystals, allowing crystalline beings to enter the Wasteland.

An ancient Saurian story of giant reptiles falling from the sky was my first clue that interplanar travel could be possible.

The hail of reptiles was summoned with a crystal, and the sky was forever darkened by haze and the ground devoid of water, leaving the land barren forever after. - exerpt from Gulpax's Collected Notes and Diagrams - Saurian Wasteland (GS-ADV5)

You find the crystalline frog in the center of the subterranean lake in the Saurian Wasteland. It is surrounded by floating corpses, dropped from above by the Saurian priests.

In its mouth, you spy the durgolium box that Zug had been carrying. You believe this artifact is important to your quest.

• Fight the frog.
  • You defeat the beast and are able to claim the box.
  • You are nearly drowned. The frog retreats deeper into the water, never to resurface.
• Use an item.
  • Trial and error reveals the secret. The ornate censer will allow you to put the frog to sleep, if used correctly.
