Lyra loves soda. She can't get enough of the stuff, honestly. Her roommate and eternally-platonic pal, Bonbon, doesn't really care a whole lot. She just kinda "flows" with it. But, Lyra's passion for soda now appears threatened. The Equestrian Health Organization wants to ban the stuff. As a mare that prides herself in her status as Ponyville's leading soda guzzler, she doesn't exactly take it that well.
So begins a not-so-epic quest, in which Lyra tries to save her favorite everytime beverage from the horrors of federal legislation. And as usual, Bonnie just gets dragged along for the ride.
A spin-off thing of the Making Muffins trilogy, because why the heck not? Also, a part of the grander Muffinverse as a whole!
