The ad, created by Quiet Storm, features prosthetic make-up by special effects company Artem.
The ad shows a man tucking into the chicken breast pieces, gradually turning from a man into a hairy beast.
Initially perturbed by the transformation, he gradually appreciates the new look and dances confidently in the mirror until his girlfriend comes home.
The new ad launches on Thursday May 1 across cinemas and TV nationwide.
Media was planned and bought by Universal McCann.
It was created by Cat Campbell and Jo Wallace, who directed the spot through Quiet Storm Films.
