On a peaceful and glorious day, Twilight Sparkle is inside her shiny new castle reading a book. She has no plans for anypony to visit her, or need to go anywhere in person. Just a nice, quiet afternoon to herself and a few dozen books. That is, until something comes crashing through her window and slaps her on the face.

It only goes downhill from there, so heighten up yer knickers, because here comes MISTER STRETCH!
