From publisher blurb: Inspired by classic fairy tales and fables, the Once Upon an Encounter series gives gamemasters quick encounters that can be inserted into any adventure or campaign. The Scorpion and the Frog is designed for a party of adventurers of 2nd or 3rd level. A paddle-driven ferry crossing a wide river as the sun rises. An insane alchemical bomber who has gone too long without listening to the voices in his head. When the bombs go off and the ferry begins to sink can the party prevent the bomber from taking the crew and passengers with him to the bottom of the river?
