The discounted pricing offer applies to Sonic’s entire lineup of Slushes, including their trio of new, movie-inspired color-changing “Transformers: The Last Knight Slushes.”
Sonic’s color-changing Slushes are available in three varieties, each inspired by the movie’s most popular characters: Optimus Prime, Bumblebee and Megatron.
The Optimus Prime Slush features a cherry Slush topped with a flavorful layer of blue raspberry. The Bumblebee Slush starts with orange Slush and a layer of grape flavor, while the Megatron Slush features a base of sweet, classic clear Slush topped with a layer of icy grape flavor.
The color change is activated by simply stirring the Slushes.
