Growing donut chain Duck Donuts has associated with the iconic rubber duck for a long time. The store offers a large selection of collectable rubber duck toys at the registers of its stores for customers to purchase.

To celebrate National Rubber Ducky Day on Monday, January 13, all Duck Donuts locations are giving away a free cinnamon sugar donut with the purchase of one of these rubber ducks. National Rubber Ducky Day originated from the television program Sesame Street. Ernie, the show’s lovable orange puppet, declared January 13 as his beloved rubber ducky bath toy’s birthday and is recognized on this day each year.

“National Rubber Ducky Day gives us the opportunity to celebrate a micro-holiday with our guests that is unique to our brand,” says Russ DiGilio, founder and CEO of Duck Donuts Franchising Company. “We originated in Duck, North Carolina, and our duck logo is a staple to our brand, as are the small rubber ducks we sell. In fact, in 2019, our 87 locations sold more than 117,000 ducks!”

As another reason for customers to visit its locations, Duck Donuts, has introduced two new limited-time flavors. From now until Monday, March 2, customers can get the rich hazelnut flavor of Nutella topped and drizzled on vanilla cake donuts. In addition, the company is bringing back the fan favorite HEATH toffee crunch topping.
