  • Jess – a black and white cat, from the BBC series Postman Pat. He is also the protagonist.

  • Mimi – a pink and white rabbit. She lives in her hutch and enjoys all things arts and crafts.
  • Baa – a sheep with a blue wooly hat and a blue and white scarf. He always hangs out with Billie, who both live up in buttercup meadow. Baa tends to be afraid of more things than the others and particularly hates getting wet because the water stays in his wool a long time, making him cold and miserable and also makes his wool heavy.
  • Billie – a fieldmouse. She is often seen with Baa and rides around on his hat, since Baa can get places faster than she can. She carries a magnifying glass and a set of binoculars so she can investigate the "big question" further.
  • Horace – a frog who wears large glasses and lives at the pond. He loves making music and instruments out of natural found objects.
