Tiny (Revolution of the Daleks)

"Tiny" was a red Pting that was imprisoned in the Judoon prison, where the Thirteenth Doctor was serving her sentence. Whilst passing its 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.
