Victoria was a snake who had a brief appearance in Sick as a Dog.
She was next to her owner when Arthur Read was at the vet because Pal was sick. Her body was tied in a knot. Her owner asked Arthur if his dog was unwell. Arthur said Pal was unwell, and the owner apologises and then states that Victoria got tied in a knot. He then tells her "Don't force it"
Victoria is a long, slightly chubby, green snake with purple spots and an off-white underbelly.
