a uninessie is a mystical creature that lives in loch ness. uninessie's mother is the loch ness monster, commonly known as nessie. It's father is, obviously, a unicorn, and a mixture of the names creates the name uninessie.
it is usually a purple color, and looks like a sea snake/monster with a unicorn horn on its head.
Here, on your left is Loch Ness, where the uninessie dwells with its mother, Nessie, and its father is over there on the hillside.

A fictional animal...a mix between a nessie, or loch ness monster and unicorn. It looks like a sea monster with a unicorn horn!
When traveling to a new world, you may experience an encounter with a uninessie in a large lake.
