Rainbow Dash was jarred a while ago, and afterwards, her jar was placed on a shelf and forgotten about. As you can imagine, that got pretty boring really fast for the former pegasus, so she's decided to make her escape. It took a lot of work, but she finally managed to unscrew the lid of her jar from the inside. Now all she has to do is hop, bounce, and wiggle her way out of whatever storage area she's being kept in. Should be a piece of cake for someone of her athletic skill!
