Buttons (TV Terrors)
From Tardis Wiki, the free Doctor Who reference
Buttons was friends with Monica and Cuthbert. After seeing Dr. Who on television, the trio decided to attempt to get Dr. Who's autograph, but they were chased by a guard at the television studio. Hiding inside Dr. Who's TARDIS, they accidentally travelled to the Stone Age, and after they were chased back into the TARDIS by a caveman, they left the TARDIS in the 20th century and were chased by the guard once again.
