Tinkle (AAAGH!)
From Tardis Wiki, the free Doctor Who reference
Mrs Tinkle was a robot humanoid that worked for AAAGH. She had the body of a robotic elderly lady.
She shared many adventures with her child colleague Nervil.
Amongst the species she met were Sea Devils, Krotons, Silents, Terileptils, Racnoss and Daleks.
The Eleventh Doctor once appeared at AAAGH to help Tinkle with one of her missions; they even shared cake.
Tinkle once met the Master in his "Harold Saxon" form. (NOTVALID: AAAGH!)
