Ever since Rarity started working out, Rainbow Dash has found herself growing jealous of her friend's ease in putting on muscle mass. To cope with her growing feelings of inadequacy, she eats—a lot.

As Rainbow balloons in weight, a very interested Rarity steps in. Cakes, pies, sweets—anything to help Rainbow's expanding waistline. Sure, Dash might be bulking up in all the wrong ways, but a plumper Rainbow Dash might turn out to be a growing attraction for the both of them. Rainbow did want to get into shape, after all.

And round is, in fact, a shape.
