Sea Encounter Enhancements

What makes this sea encounter different?

Maybe the crate of chickens floats in the water or a fishing boat is adrift. Maybe there is a wagon stacked with barrels or stepping stones over a stream. A creature might have a chest of fancy clothes or a feather that turns into a swan boat. There might be singing from below the waves or sahuagin lurking nearby.

There is a 5e random encounter generator at ChaosGen. And also a pdf of these and more tables at the DM's Guild as Sea Encounters.
