Peppa's family consists of Daddy Pig, Mummy Pig, Peppa, and her little brother George. Daddy Pig is a bit bumbling and eats too much - "Daddy's big tummy" is a frequent source of jokes - while Mummy Pig is far more sensible and practical than Daddy. There are also Grandpa and Granny Pig.
The characters all wear clothes, live in houses, and drive cars, but still display some characteristics of the animals on which they are based. Peppa Pig is very bossy and is a bit mean to her little brother George. Peppa and her family snort like pigs during conversations and also like to jump in muddy puddles.
