Snapping turtle

The Snapping Turtle is a type of large fish that can be found at night in the river in. Its shadow is the same size as that of the Black Bass, a far more common river fish.

Donating in New Horizons
"The snapping turtle is a large turtle known for its crocodile-like body and long claws. No, wait—it is better known for its ferocious bite, which it can deliver with shocking speed for a turtle. NO, WAIT—it is BEST known for that time one chased me across a parking lot and I had to climb on top of a car."

When donated, it can be found in the larger pond of the fish exhibit, standing on top of the log.

Trivia

 * When placed down, it does not have any form of tank or container, simply staying in place. If interacted with, it hisses and snaps its jaws.
