Pinkie Pie's made cupcakes and Twilight's craving for them. The girls are a bit surprised by Twilight's sudden sweet tooth. And Rainbow, stop making accusations. There's no way Pinkie's a witch.
For those who don't know, sweet tooth is a term for a great liking for sweet tasting foods.

If you've watched MLP: Pony Life, you'll know there's a couple of episodes where Twilight gets chubby from eating a lot of Pinkie Pie's treats, including the Pie vs Pie episode. And that's what gave me this idea. Even the Princess of Friendship can't resist the sweets, and that Friends Forever comic issue is the proof.

I think Pony Life is alright. It has a much, much funnier and lighter tone than Friendship Is Magic. And honestly, I prefer it over Teen Titans Go!.
Man… I feel like it's been a long time since I drew ponies or something.
Hope you guys like the art!
