Witiku

The Witiku were a species of humanoids, mutated from Laylorans.

Biology
The Witiku were hairy, four-armed humanoids. They had long talons and looked like woolly gorillas. They were allergic to Jinnera. (PROSE: The Price of Paradise)

History
The Witiku were linked to the ancient past of Laylora, and were historical figures who came when disaster happened on the planet. When the Tenth Doctor and Rose came to Laylora, they were attacked by several Wikitus. The creatures, however, eventually found out that they had a weakness to the potion Jinnera and were finally defeated when an earthquake hit Laylora. (PROSE: The Price of Paradise)
