All three dessert drinks are made with the chain's vanilla ice cream (the shakes are made with milk and ice cream, the ice cream slushes are a combination of the chain's signature ice slushes with ice cream, and the floats are ice cream with soda).
The one-day deal highlights the launch of the chain's "Sonic Nights" promotion where you can get all shakes, ice cream slushes, and floats for half price after 8 PM daily from now through the end of summer.
