After Alex jumps to his apparent death but before he regains consciousness in a hospital, he awakens to find a pink pony talking to some lint, rocks, and a sack of flour. Even more curious, he discovers that he, himself, has turned into a pony. Thinking this is a dream, he confides in the pink pony and asks her whatever is the matter?
Alternate history. If Pinkie Pie had gone crazy in Party of One, with the help of your humble narrator, Alex.
