This is how The Story of Snowstorm goes in A Hearth's Warming Tail.
Starlight Glimmer: (narrating) Every home in Canterlot was filled with holiday spirit. Every home... except one. It was said of Snowstorm that he was almost as studied as Alpha Trion. Almost, since everypony knows that Alpha Trion was an expert at everything from transfiguration, dimensional calibration, teleportation—anything you could possible imagine. The point is, Snowstorm was also a powerful Transformer. He wanted to be perfect. Anything that got in the way of that was a waste of time. Snowstorm despised Hearth's Warming, the whole Hearth's Warming year. One Hearth's Warming, he was studying and was distracted by bells outside.
Snowstorm: (grunts) If only I could just erase this holiday.
Starlight Glimmer: (narrating) But the bells just kept putting him off. He eventually had to have his loyal assistant, Snowspeed, to help him clean up the mess that had been made during the bell disturbance.
Snowspeed: Happy Hearth's Warming, Snowstorm.
Snowstorm: What don't you get, Snowspeed, about my point? Hearth's Warming is a menace. A dangerous day for all of Equestria.
Snowspeed: What are you talking about? It's how we remember the defeat of the Windigos.
Snowstorm: The Windigos let themselves be defeated.
