Figment (Beforwards)

Figment once went for a walk in the Thousand Year Wood. (PROSE: Beforwards, Afterwords)

He wore the same spacesuit that the Space pig encountered by the Ninth Doctor had worn. (TV: Aliens of London)

Behind the scenes
Figment is a clear parody of the Winnie the Pooh character, Piglet and wore the costume of the Space pig from Aliens of London.
