S1·E18 The Glass Princess (3)

The Raptorians discover that the captured ponies' hair grows back instantly once cut off. Not only are Lickety-Split, Gusty, and Heart Throb then forced to stay, but they are also ordered to weave Porcina's new cloak themselves. The search party is reunited with the catpured ponies only after the magic cloak has been finished and delivered to Porcina. The captives inform the others of Porcina's threat to turn Ponyland into glass and the Raptorians' plan to claim it as their new kingsom. Before anything can be done, Porcina has cast a spell through her mirror that turns all of Ponyland and every creature living there into glass.
