Beating the Heat is another My Little Pony Friendship Is Magic Fanfic by Andrew J. Talon, he of Progress fame, and co-written by The Sage of Toads and Friendly Uncle. Twilight Sparkle is acting a bit... off, and she's not the only one... It can be found here, here, and here. It used to be on Spacebattles before the authors received infractions from the mods. Not to be confused with SomeGuy's earlier My Little Pony Friendship Is Magic Fanfic Beating the Heat.
