The newest episode of My Little Pony Friendship is Magic had Pinkie Pie do a rap to help Rainbow Dash study for her Wonderbolts test. Here's a video
I thought it was really good and funny. It was a reference to 90 video's with the aspect ratio and the way it looked. Pinkie Pie has been really good this season.I loved when she kept terrifying Fluttershy while trying to help.
