TPotW: Tentacles feat. Amy. (Patreon)

I managed to finish it. I even came up with a simple backstory for no reason. The attached zipfile contains 3 extra shots, including a futa version. 4k resolution baby.

Below Greenhill zone, there is a cave system that contains a different vegetation. While it looks the same, the plants and flowers glow in the dark. The glow effect is partially due to the strange liquid that fills the caves. 

It's unknown what lives down there. but reports have stated that a weird, water-like, creature has been seen roaming around. Sometimes it just stares at the scientists with it's green eyes. Other times it flees by becoming a liquid. Reports also state that tentacles can appear and reappear like the creature. It has yet to be caught.
