Rarity tried for the rope again, this time with more fervor and tenacity poured into her gnawing, not caring if the fibers of the twine were getting stuck in her teeth. Rarity bit and ground at the rope, lighting her horn so she could see her work, bathing her little corner in a cerulean aura. Once it was thin enough, she pulled at the rope with her magic and neck until it snapped. Leaving only the loop around her neck, and a bit of twine hanging below.
