Silverscale Crocodile

It’s a crocodile. With silver scales. Tieflings ride these guys all the time. Just like other people ride Chocobos.
Silverscale wrastlin’ is a fun recreational activity that has been widely described as “fun for the whole family” and “the most fun you’ll ever have while losing an arm to a dangerous wild animal.” They are most easily subdued by sedating and/or suffocating them, which renders the beast quite docile/limp.
