Spectral Siren

A shimmering blue cat spirit, taking the form of a calico, has somehow manifested within your home, drawn in by the allure of the music humming through your open window. You come across the spirit playfully dipping its paws into a puddle of moonlight on the floor, as if it were the ocean's surface. Attempting to catch its attention, you play a tune on your saxophone, and the spirit's eyes light up with childlike wonder, eagerly approaching the sound.
