I watched this episode about.......I lost count after I first saw it. If you saw this character is real then why did Rainbow Dash tell a story about it, then suddenly became a dream. Well that was the purpose until Hasbro decided to make this character from Scootaloo's dream an actual character. Here there's your fucking answer.
i have, no go scare this pony, *show picture of glam a shadow pony* and i'll give back to you, *watches then waits for the scream* AHHHHHHHH! *she run away then stops* keep the shoe i'm getting out of here!
I think I know what this is based on. Mark Twain had a similar ghost story, with a spectral voice asking, "Who's got my golden arm?" And the catch to scare your audience is to scream out "YOU'VE got it!!"
