A small white snake with |_| eyes and a small blue bow, introduced as part of Ouro Kronii's New Year's outfit in January 2022. Despite the bow he is referred as "he" by Kronii and thus canonically male. He sits on Kronii's white fur boa as seen in post #5058008 (Note: the white snake with red eyes on Kronii's obi is not another snake, but merely a static decoration)
The names Ouro and Boros are derived from the ouroboros, a symbol of eternity.
