The Baby appears in the Creature Shop movie Alice in Wonderland. A querulous, somewhat grotesque infant, the baby apparently belongs to The Duchess, where he's shaken and subjected to the effects of pepper and The Cook's tantrums. Alice attempts to rescue the baby, but the moment they get out of the house, he turns into a live pig.
The Alice in Wonderland baby had previously appeared in The Muppet Show episode 406, as a background character accompanying the Duchess. The baby was one of Bobby Benson's babies, and later on, is replaced by a piglet, reflecting the transformation in the book.
