Taco Bell’s own description on the ordering menu: “Your choice of a Dirty Soda, Taco Bell Energy, and Agua Refresca.” The drink slot in the description is filled at the counter; the table above shows what each fountain choice adds.
How the total is built
Three Drink Theory Kit is drinks only: the ordering menu lists three drink slots (Mountain Dew Baja Blast Dirty Soda, Large, Pineapple Citrus Energy, Medium and Strawberry Passionfruit Agua Refresca, Medium), each swapped at the counter for any fountain choice at that size. The listing prints 680 calories, which is the default choice in every slot; the table above shows what each fountain flavor adds at the slot size, and no total is summed here because the choice is the reader’s.
