Shellycoat is a mystical creature from Scottish folklore, known for its mischievous and elusive nature. Often depicted as a water-dwelling spirit, Shellycoat is said to inhabit rivers, streams, and coastal areas.

Its appearance is described as being covered in shells and seaweed, which serve as its distinctive coat. Shellycoat delights in playing pranks on unsuspecting travelers, leading them astray or causing confusion with its eerie laughter and mysterious presence.

While not inherently malevolent, encountering Shellycoat can be disconcerting due to its unpredictable nature. Legends suggest that appeasing Shellycoat with offerings or polite gestures may mitigate its tricks, allowing travelers to pass through its domain unharmed.
