The Regress Shell is a flora species that is generally found in deeper biomes. It is purely decorative.

By cutting the plant with the knife, the player can obtain Regress Shell Seeds.


The Regress Shell is composed of multiple layers of gradually growing red rings, connected to an orange stem by a couple of small tendrils.

The tendrils are white tipped, forming a circle of radiating white beam-like patterns capable of emitting bright bioluminescent glows.
