Mate (Pugwash Ahoy!)

A member of Captain Pugwash's crew held his gun towards the First Doctor when his TARDIS materialised on the ship. (NOTVALID: Pugwash Ahoy!)

Behind the scenes
Master Mate was not named in NOTVALID: Pugwash Ahoy!, as he would be recognisable to the usual audience of Captain Pugwash. His name was a pun, intended to sound like 'masturbation'.
