The Rani's menagerie

The Rani's Menagerie was a collection of every creature and machine in the universe held on the Rani's TARDIS.

Appearance
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. (NOTDWU: Dimensions in Time)

According to the Rani, the only creature missing from her menagerie was a human. The known members of the menagerie, however, are:
 * Argolin

 * Cyberman
 * Stigorax
 * Mentor
 * Ogron
 * Sandminer robot
 * Sea Devil
 * Tetrap
 * Time Lord

Behind the scenes

 * The Daleks were to have featured in Dimensions in Time (the segment was shot), presumably as part of the Rani's menagerie, but due to disputes with Terry Nation's estate, they were removed. (DWM 324)
