Periwinkle is an armless periwinkle creature. He closely resembles a lizard with 2 legs on the sides. His head also resembles a magnet or anchor separated into an upper and lower jaw, as he is still small and is not fully grown, he only has a few small teeth. But they're still sharp!

Just like his dad, he is manipulative. He is also playful, and vicious. He tricked Cyan into thinking he was her son along with Navy tricking Cyan into thinking he was her husband just to take advantage of her.
