Colton Haynes makes his “Scream Queens” debut as Tyler in tonight’s Season 2, episode 2, titled “Warts and All.” Hours before the episode goes on air, Haynes took to Instagram to share a close-up photo of his character — a patient with a hideous ailment who checks into C.U.R.E. Institute Hospital in hopes of a cure.

Haynes is completely unrecognizable in his role, since he is covered in warts of all shapes and sizes from head to toe. His skin disease appears to have affected every inch of his body with no area of untouched skin in sight. In his Instagram post, the 28-year-old actor revealed that it took him five hours of full body prosthetic makeup to achieve his “Scream Queens” look.

Haynes reprises his role next episode, as his name is still included in the guest cast list for episode 3, titled “Handidates.”

In an Instagram post Haynes shared six weeks ago, the “Arrow” actor briefly talked about his experience on the set of the comedy-horror series.

“I am having such an amazing time on this show with ppl who are too talented for their own good!!!”  Haynes captioned a photo of himself hanging out with “Scream Queens” stars Emma Roberts (Chanel), Billie Lourd (Chanel #3) and Abigail Breslin (Chanel #5) on the set of the show.

He then gave co-star Jamie Lee Curtis a shoutout, writing that she’s “one of the sweetest people” he has ever met. “She has embraced me like I’m her own son,” he said of Curtis who plays Cathy Munsch in the series.

“Scream Queens” Season 2 airs every Tuesday at 9 p.m. on FOX. Check out the synopsis for next week’s episode:

“Determined to find out who the killer is, Dean Munsch, Denise (Niecy Nash) and the Chanels question Hester (Lea Michele), as well as the sole survivor (Alec Mapa) of the Halloween massacre.
