Mummy Pig, known for doing “very important work” on her computer, and Daddy Pig, who “takes big numbers, transmutes them and calculates their load-bearing tangents,” are already proud parents to Peppa, four, and George, two.

Peppa Pig ’s mother is pregnant with her third piglet. The long-running animated series will be forever changed in an episode that will premiere – appropriately – on Mother’s Day (30 March).
