Tails, also known as Miles Prower, or "Timeship Tails", is a yellow anthropomorphic fox in possession of a timeship, or TARDIS. He is often happy, and a little jovial, as well as intelligent. He now often wears a scarf, in a variety of colors, work boots, brown work gloves, and goggles. They've come back to Mobius to buy some Xion crystals, mislabeled as "Sapphire Selenite" in order to make new components, or repair old ones, to keep their timeship in working order.
