Below Elephant Rock
As the handles are squeezed, the statue slowly slides forward and dumps the contents of the urn upon them, cascading neatly over the diving bell, and flowing into the channels, leading the water into the pool. In under two minutes, the entire pool is filled and continues on to the door. The moment the water touches the door, it rings faintly and opens just a bit.
A small black box slides out of a hidden compartment. The two earn the contents: a pair of gold bracelets, labeled "Chosen's Fortitude" in the liner of the box, and a long tooth about a foot in length labelled "Baby Tusk of St. Bhana."
They also earn a soaking for clever cheating, as a big blast of water will spout from the urn the moment Lucas reverts to normal, after which it falls silent immediately.
