One lovely day in Ponyville an unscheduled storm approaches. Despite the best efforts of the weather team, the storm arrived anyway. Upon its arrival it unleashes a deluge of..Cupcakes?

Which leads to Twilight being mightily confused over pastries falling from the sky. But as her friends are happy to point out, this isn't the first storm of it's kind in Ponyville.

In fact it seems unusual things raining from storm clouds is an annual event. Cupcakes being the least worrisome of objects to rain down upon the town.
