From December 2016 to January 2017 in the United States and international countries, McDonald's ran a Happy Meal promotion for toys based on the characters from Sing. Each Happy Meal ordered would come with one of the toys.
Each Happy Meal toy came with a circular piece of cardboard with a character on it meant for the toy to be stood on.
In the United States, the following toys were offered as part of the promotion:
Buster Moon; says "Hahahahaha, ya! Gonna spice things up on stage!" when clapped near or pressed on a hard surface.
Rosita; sings the first parts of the chorus for "Firework" when clapped near or pressed on a hard surface.
Gunter; says "Alright, piggy power! Hahahaha!" when clapped near or pressed on a hard surface.
Mike; has a pull-back motor that allows him to move forward for a few seconds.
The Q-Teez; their hands can be moved up and down by pressing a lever.
The commercial for the toys, also ran from December 2016-January 2017 on multiple television networks across the United States, was a 30-second animated short (also animated at Illumination Mac Guff) that included several characters (the sheep, the hippo, Sherry-Anne, Johnny, Ray, and Rosita along with her children) ordering a Happy Meal and additional items at a McDonald's drive-thru. Each character sang their part of the order, with Rosita's piglets singing their order to end the song. Miss Crawly was portrayed as the cashier at the McDonald's restaurant, suggesting that Rosita pop the trunk of her car to fit all of the Happy Meal boxes. The commercial ends with the piglets eating (and one singing with a Happy Meal box over his head) in the kitchen at their house.
