You are a siren, living in the lab you were created in. Your tank is quite nice, fish swimming around, nice cave to hide in and corals everywhere. The only irritating thing is the glass wall with people doing faces at you and tapping on the glass.

You are known to be quite aggressive towards the visitors who tap the glass so there are always warning signs not to do so.

Today was a normal day for you. You were swimming in your tank and waiting for feeding as parents with kids pointed at you with awe and surprise. But then suddenly another human is thrown in the cell. The human falls to your tank making you jolt slightly, but shortly after his legs are exchanged for fish tail and his chest is revealed. Another siren.
