Rainbow knows she has it bad when she starts seeing her in the cloud formations. There's a pretty big difference between Pinkie and a massive cumulonimbus cloud, but she just can't see it; the fluffy vapour looks altogether too much like her mane, curls upon curls.
Meditatively she sculpts, and wonders if this is what her mane would feel like; fluffy, bouncy, insubstantial. But insubstantial is the wrong word, for her.
Before she knows it, she's finished, and stands back to admire her work. She never realised that storm clouds could be beautiful before.
Not that she'd ever admit it.
The best days are spent with friends, so Pinkie's delighted when Twilight and Fluttershy burst into Cupcake Corner. Twilight drags her outside, points to the clouds and asks, "Pinkie, is this your doing?"
It isn't, but she likes it. Everypony should have an awesome cloud version of themselves.
"Ooh! Idea! I should make Dashie cookies!" she shouts, and offers no explanations.
"I don't get those two. Oh well," Twilight sighs, shaking her head. "I suppose we'll be the first ponies ever to have eaten Rainbow Dash."
Fluttershy squeaks and breaks out in a luminescent blush. She refuses to explain why.
