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 a "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.
