Jimmy Fallon seems to be a funny guy, but The Tonight Show host has a spooky side, too, as Prince Harry found out firsthand when he braved Fallon’s new Tonightmares haunted maze experience in a video shared Thursday.

The terrifying attraction, located in New York City’s Rockefeller Center, sent Harry screaming, like that time when he saw something creeping and innocently asked, “Is that a panda?” Before the figure he had been eyeing made a quick move.

“You’re afraid of pandas!” Fallon accused his guest. “No, I’m not!” Prince Harry insisted. Both were screaming — and panicking.

Watch the prince’s full American-style haunted house experience in the video below:

Harry really jumped when a man who appeared to be a ghoul appeared out of the darkness holding a lead pipe.

At one point, the two saw a bloody man that made Harry ask jokingly, “Is that Michael Bublé?”

Fallon agree and told the character, “You do a great job on The Voice,” the NBC singing competition that Bublé joined as a judge this year.

After a scary scene set at a dental office, the video shows the haunted maze actors freaking out — mouths open and hands fanning the face — that they had just seen Prince Harry.

There was one final heart-pounding moment at the end, as a character popped up when the guys were taking a photo.

Prince Harry reacted as if he were going to punch someone, before he smiled.

At the beginning of their adventure, Fallon had asked Harry if he were easily scared, to which he had accurately predicted there would be trouble: “Not normally, but today might be different,” he said.

Tonightmares is open Tuesday through Sunday now through Halloween. Tickets and more information are available at jimmyfallonstonightmares.com.
