While practicing transformation spells, Twilight accidentally hits Spike, temporarily trapping him in a colt's body. While Twilight tries finding the solution to turn Spike back, he has to learn about his new body, and a new bit of information from Applebloom that might change his life for years to come.

(Note: This is a story I wrote quite some time ago, and was originally published in full on DA a little over a year ago. Also, as a heads up, I know the first three chapters aren't exactly very high quality, they were written and published on DA before my editor became a brony and I was more comfortable sending him my stuff. The chapters after that though (4 and onward) are in better quality, I can promise that. Also, this is set around mid-season 2, to kinda understand why certain factors were left out.)
