The Cavern of the Fountain Beast

An underground lake has dried up, replaced by a strange water that causes the skin to itch and burn. If you investigate, you will find what (or who) is cluttering the source — as well as an interested third party.

The entrance and exits to the cavern are left vague so you can plug it anywhere you want in your own game. If you wish to play this dungeon on its own, you can replace the olm hermit by a party of mice villagers concerned that their source is not running anymore.

My french countrymen might identify the inspiration for this encounter as a specific scene in a certain animated movie.
