After Emily had left, Bagpuss woke up. The programme shifted from sepia to colour stop motion film, and various toys in the shop came to life: Gabriel the toad (who, unlike most Smallfilms characters, could move by a special device beneath his can without the use of stop motion animation) and a rag doll called Madeleine. The wooden woodpecker bookend became the drily academic Professor Yaffle (based on the philosopher Bertrand Russell, whom Postgate had once met), while the mice carved on the side of the "mouse organ" (a small mechanical pipe organ that played rolls of music) woke up and scurried around, singing in high-pitched voices. Sandra Kerr and John Faulkner provided the voices of Madeleine and Gabriel respectively, and put together and performed all the folk songs. All the other voices (including the narrator and one out-of-tune mouse) were provided by Postgate, who also wrote the stories.
