Inside a crate on level 1, you find
An odd Seashell, unknown to Science, marked in vivid, natural purple patterns.
If you put it to your ear, the sound is beautiful, like Angels singing. Enthralling and delightful, it fills you with joy.
Under the effects of the sound, you begin to notice that everything is changing color, to vibrant, almost fluorescent, shades. And the Universe begins to swirl around you, as you sink into a rapture of Utter, Cosmic Bliss.
Unconsciousness quickly claims you.
The Organism in the shell extends its ovipositor into your ear.
The eggs will begin to hatch in about a year.
