While everyone has been squawking about Shake Shack’s latest chicken addition (the Salt & Pepper Honey Chick’n), we’re much more excited about the fast food giant’s pact with Yummy World. Tomorrow, Friday, October 7, Shake Shack is teaming up with Kidrobot to transform the Madison Square Park Shack into a one-day only “Yummy World”, inspired by the designer toy company’s cute-as-can-be Yummy World collection. Throughout the day the location will be serving up a limited edition Yummy World concrete. The frosty dessert is made up of vanilla frozen custard blended with Doughnut Plant doughnuts, rainbow sprinkles and strawberry jam. Each order of a Yummy World concrete comes with a complimentary Yummy World Blind Box Keychain (while supplies last).

Kidrobot’s Yummy World is a line of toys inspired by snacks, fruits and desserts. The characters in the collection live in the town of Sprinkle Tree and each one has a name and a story of its own. From Cheezy Pie and Flaco Taco, to Melony Watermelon, these guys are absolutely adorable. They come in plush, vinyl and as keychains. Kidrobot recently introduced a line of Yummy World Red Carpet Keychains, which features characters such as Soft Serve Sally, Connie Cotton Candy and Bubba Burger. They go for $4.99 each.

If you want to get in on this yumminess, head to Madison Square Park Shack on Friday, October 7, 2016 between 11am-11pm. For more information visit Shake Shack’s website.
