Ood (Pond Life)
From Tardis Wiki, the free Doctor Who reference
An Ood equipped with a translation sphere was rescued from the Androvax conflict by the Eleventh Doctor. While on his way back to the Ood Sphere, the Doctor briefly visited Amy Pond and Rory Williams in London one June in the 21st century. The Ood wandered out of the TARDIS and ended up in Amy and Rory's bathroom. A month later, the Ood was still with them, serving as their butler. The Doctor returned it to the Ood hivemind before the end of the summer. (WC: Pond Life)
