Tiny (Revolution of the Daleks)

Tiny was a Pting that found itself imprisoned inside the same prison as the Thirteenth Doctor. Whilst passing it's cell, the Doctor stopped to speak with the creature, which appeared to be agitated as it roared at her. The Doctor informed Tiny that there was no use trying to escape by eating the cell, as she had already tried this tactic. Tiny replied by growling at the Doctor briefly before she moved on.
