Imagine the mane6 are at an abandoned playground or maybe it’s being remade, and they start playing with the abandoned objects and Twilight picks up a swing from the ground, and she flies up so Rarity can sit on the swing and you just have Rarity swinging on it and they’re both giggling like fillies AND ISN’T THAT THE CUTEST THING EVER YES IT IS
I considered your idea then remembered Twilight’s a giant nerd who doesn’t exercise enough.
