Tiderunner

A long mudskipper with a sail of a fin that runs the tide line, half fish, half lizard. It hunts by feeling footsteps through the wet sand, and can call the sea up the beach for a moment and ride it. Frost stops the water under it dead.

How it fights

It slaps the wet sand and listens: ripples run out under your feet whenever you move. Then a surge comes up the sand and it rides it at where your footsteps are heading. Freeze when the ripples show - standing still, it cannot feel you and lunges blind. Afterwards it lies stranded, flopping.

Where to find it
