The Hobothies were large yellow beings with big purple eyes. Their species were capable of mind control. They could channel their influence through materials like ink. One Hobothy planned to take over the Earth in 1840, using the Penny Black stamp containing ink it had infused to do so. Rose Tyler pushed the Hobothy into a printing press, and the Hobothy was crushed by the press operator Thomas Scott. (PROSE: Stamp of Approval)
