Ranboo is an 11 year old Siren whose mother is Sally, a salmon-siren hybrid. Ranboo himself is an axolotl-siren hybrid. He loves singing, but hates rumors of sirens having a deadly singing voice, which isn't true. He has pointy canines like normal sirens, black and white tail, scales, and fluffy brown hair tangled with seaweed as what he says is a fashion statement.
