kelpy

One afternoon Reeves took a fancy to revisit the Kelpy's Cave.

Shellycoat must not be confounded with Kelpy, a water spirit also, but of a much more powerful and malignant nature.

At low tide we can walk right around, but when the tide comes in it fills the Kelpy's Cave.

"The kelpy would have been sure of its victim then," he said, trying to speak lightly.

Anders had heard a story something like that, only it was about a water kelpy, not a brownie.
