Spirimur uses its spectral body as ears that are highly sensitive to loud noises. If the noise around it gets to be too much to handle, it vibrates its keystone, creating a loud screeching noise that hopefully drives off the source of the noise.

At rest, Spirimur looks like a regular keystone, but when picked up it lets out a banshee-like wail and runs off once dropped. The way to tell the difference between a Spirimur and a keystone is to listen for any murmuring sounds.

Its cries equal a jet plane in volume. A Pokémon that was formed by 108 spirits.
