All Bottled Up.While Twilight and her friends are away on a friendship retreat, Starlight remains at the castle to help Trixie practice her magic. Trixie carelessly uses a teleportation spell on Twilight's Cutie Map, sending it to an unknown location. Starlight's rage causes a red cloud of magic to spew from her horn, which she contains in a glass bottle for fear of hurting Trixie. During their search for the map, Starlight's anger at Trixie continues to mount until the bottle accidentally breaks and releases the cloud, which infects other nearby ponies and makes them attack Trixie. Starlight is able to dispel the cloud by venting her anger to Trixie, who apologizes. The two find the map at the spa where they first met, and return it to the castle just as Twilight and her friends arrive.
