Shedno itself rarely moves, but mysteriously, the pendulum it holds always does. People have reported Shedno sometimes changing positions if they look away from it, and others have reported finding themselves asleep if they look away too long.

The arcing movement and glitter of the pendulum in a Shedno's hand lull the foe into deep hypnosis. A peculiar Pokémon that floats in air even though its wings remain completely still.
