Tetranadon

Description

This gluttonous Amphibian waits in deep waters for prey, which
it will swallow whole along with nearby rocks and dirt. It is also
known to flatten prey beneath its crushing weight.

This monster swallows rocks to aid digestion by pulverizing its
meal inside the stomach. Once its prey has been partially digested,
it will spit up the rocks, water, and anything inedible.

The disc-like protrusion on its skull protects moisturizing organs
essential for land activity. This disc becomes more blue over the
years, and unblemished discs are used as fine tableware.
