Based on art by R1verRed on DeviantArt: https://www.deviantart.com/r1verred/art/Young-River-942227307 River is a purple Scax, which is a hybrid of a cat, fox, & skunk. He had a nightmare about dying by, unconventional means (aka inflating & popping like a balloon, because that's one of the artist's main things) & he needs comfort badly. He's fairly young, around 4 to 6 years old.
