Oculus

The Oculus is a life form belonging to the fauna category. It can only be found in Jelly Shroom Caves.

The Oculus is catchable and edible, raw or cooked.

Appearance
The Oculus is a small, dark grey fish that looks very similar in appearance to the Peeper, although around twice the size.

It has two large bioluminescent purple eyes, with each featuring very detailed irises, and appears to have no visible mouth.

The Oculus has two tube-like organs that extend from its body to the top and the bottom of its head, which resemble backward-facing jets pushing it forward, much like how a Peeper maneuvers in the water. Its body ends with five swaying stalks for a tail, each having multiple purple stripes.

Behavior
The Oculus will not flee from the player when approached.

It seems to be afraid of light, as any light source directly pointed at it will make it flee. This is consistent with its DNA serum being Light Sensitivity.

Data Entry
This specimen shares genetic similarities with the common Peeper. The two species evolutionary history must have diverged as the Oculus developed specialized apparatus for navigating caves. Proximity to Jellyshrooms suggest these may be the Oculus' primary foodstuff.

Trivia

 * The Oculus seems to be a subspecies of Peeper, adapted to live in low-light environments.
