The Grinch loves a good Krispy Kreme donut!

The popular bakery “transformed into Who-Ville overnight” and turned all of its original glazed donuts green. Krispy Kreme is now offering a free Original Jar Dozen with the purchase of any regular-priced dozen – including the special Grinch Green Dozen.

Offer available on December 13th and 14th in store or drive-thru only. The limit is two dozen per guest, while supplies last.

The launch of the Grinch Green Dozen offer comes after Krispy Kreme turned its annual “Day of the Dozens” offer – which typically offers an Original Glazed Dozen for $1 with the purchase of another dozen – into a “Buy One, “get one free” offer has changed.

Krispy Kreme posted a few videos on Instagram in which the Grinch can be seen sneaking into one of its stores, eating some donuts and dyeing the donut dough fluorescent green. The Grinch bore a striking resemblance to Jim Carrey’s version of the beloved Christmas villain.

In a second video, the Grinch was once again seen in Krispy Kreme’s kitchen, this time working with employees to create the perfect green donut.

On November 29, the chain introduced three new ones How the Grinch Stole Christmas!-Themed donuts.

The trio of offerings in the Merry Grinchmas Donut Collection are each inspired by a different character from the popular Dr. Seuss story inspired: Grinch Donut, Grinchy Claus Donut and Cindy-Lou Who Merry Berry Tree Donut.
