'Arrow' Star Colton Haynes Stuns As Ursula - Amazing (VIDEO)

Colton Haynes lit up the Internet on Sunday when he shared unrecognizable photos of himself as Ursula from "The Little Mermaid."

Wow! I did not know Colton took Halloween costumes so seriously.

Last year he was Princess Fiona from "Shrek."

Really nice! Colton has appeared on "Arrow" and "Teen Wolf."

Poor unfortunate souls #Ursula
