Cybermat (Doctor Who? 94)
From Tardis Wiki, the free Doctor Who reference
In Earth-33⅓, a Cybermat often sat on the shoulder of its Cyberman master while he played the accordion to the general public as a method of earning a living between their appearances in Doctor Who. It would sometimes klink a mug to gesture for donations. (COMIC: Doctor Who? 94 [+]Loading...["Doctor Who? (DWM 94 comic story)"])
