The Golden Lagoon of White Agony Plains is an underground lake full of molten gold that Scrooge McDuck and Goldie O'Gilt went looking for together during the Klondike Gold Rush and failed to find due to the interference of the Glacier Monster of the Klondike. Their second attempt at finding the lagoon centuries later resulted in them finding the molten gold and Goldie stealing most of it from a pursuing Flintheart Glomgold. It appeared in the DuckTales (2017) episode The Golden Lagoon of White Agony Plains!
