Description:
Twilight Sparkle was so eager to join in Pinkie’s poopy fun, she ended up turning herself into another Pinkie Pie! What a spine-tingling twist ending for this chilling SPOOPTOBER tale! Be careful what you wish for, or you too might transform into a happy pink pony who has fun all the time!…Hmm, that’s not much of a threat, now that I say it out loud.
