Crooked World

The Crooked World was a planet thats fabric and beings that inhabited it could be shaped by the thoughts of outsiders to the world.

History
A human girl crashed on the planet in an escape capsule and starved to death within days. The child's thoughts and memories shaped the planet into a cartoon world, populated by cartoon characters that lived their lives in a meaningless, repetitive existence. When the TARDIS arrived on the planet, the Eighth Doctor and his companions accidentally gave the inhabitants free will. (EDA: The Crooked World)
