Sandcars

When Figment found the Doctor's TARDIS, he remarked, "How terribly nice of Officer Sandcars." Figment wondered what he looked like. (PROSE: Beforwards) By sunset the same day Figment had still not met him. (PROSE: Afterwords)

Trivia
Given that a common feature of the Winnie-The-Pooh stories, the stories Beforewards and Afterwords were based on, was to have characters mistake words and phrases for names, it is likely that Figment never realised that Officer Sandcars never existed. Indeed, it is possible that Piglet simply mistook the notice 'Officers and cars respond to all calls' on the TARDIS for being a notice that concerned one single police officer, instead of a whole police body.
