Behind the scenes

 * Sooty was one of the main characters of the children's puppet television series The Sooty Show, along with Sweep and Soo, who have thus far only been referenced in the DWU as the names of Juggernauts.
 * The short story, It's Raining Gin, (part of the Curse of Fanfic! charity anthology published by Obverse Books), showed that Sooty, Sweep, and Sue (the puppets) were good friends of Iris Wildthyme and Panda, having several adventures together. The story would give an explanation as to why Sooty is mute - as Wombats from Metebelis IV stole it his voice.
