The product, which debuted in the Middle East in April, was brought to the U.S. at the beginning of November to the delight of many American customers.

To celebrate the product's arrival in the U.S., the restaurant chain surprised a few families in Orem, Utah with a special delivery.

What the families expected to be routine pizza deliveries, quickly turned into holiday flash-mob extravaganzas.

"Rather than being greeted by a typical pizza delivery driver, these families were treated to a flash mob in their very own front yard, complete with holiday carolers, a live handbell performance, two full choirs, a big brass band and an electric guitar solo, all resulting in one absolutely epic holiday pizza delivery," a Pizza Hut representative told News965.
