The Rani's menagerie was a collection of every creature and machine in the universe held on the Rani's TARDIS. The creatures in the menagerie were held within the walls of the Rani's TARDIS. They were covered by roundels, which could be removed to view the creature beneath.
According to the Rani, the only creature missing from her menagerie was a human. The known members of the menagerie, however, were an Argolin, a biomechanoid, a Cyberman, Fifi, a Mentor, an Ogron, a Sandminer robot, a Sea Devil, a Tetrap, a Time Lord, a Tractator, a Vanir, a Vervoid, an Aldeberian and Zog.
