As the mom of a five year old who loves My Little Pony, I found myself having to explain to KT what that picture was.
KT: "Mom, why is that man playing with Twilight Sparkle and why did he dress her in a costume like that? She wouldn't like to wear that!"
Me: "Don't worry about it, let's move on."
If you want to sit in your mom's basement and watch it and collect toys and stuffed animals that's fine, but bringing a modified pony toy to a children's theme park as a grown man is certainly a bit much.
