"Now this is the way to spend a Sunday afternoon!" the tubby pegasus smiled as she reached into the bowl of colorful candies beside her. Coming up with a plentiful hoofful of the delicious treats, she eagerly tossed them into her mouth, savoring the mix of different flavors as she chewed them with as much grace was possible when it came to eating candy."

An old pic based around some headcanon. My personal headcanon for Flitter and Cloud Chaser has been that Chaser is the active athletic one of the two(given that she is /was a Wonderbolts recruit derpibooru.org/183560) while Flitter while active also has a big appetite(no where near as big as Pinkie's of course) resulting in her being quite the chubby pony. She doesn't let the extra weight slow her down but she certainly won't be setting any speed records anytime soon.
