Rebecca is a pale cream rabbit with a pink nose, dark pink lips, and pale pink cheeks. She wears black shoes and a cyan dress. She has a small, fluffy cotton tail.
Rebecca is very sweet, loving and forgiving, but stern when she sees injustice or immorality. She is a good friend of Peppa Pig, but sometimes fights occur.
Rebecca is very protective with her little brother, Richard Rabbit. Sometimes she is bossy like Peppa as seen in the episode "Dens" where the kids could not get into Peppa's treehouse.
Peppa sometimes fights with Rebecca, this is because as it is shown in one of the series' episode "George's Friend".
In the episode "The Time Capsule", she mentioned things to the people in the future a carrot, laughs and blushes.
She always hides her great admiration for eating carrot, though she doesn't only eat carrots, but also other things. But she doesn't like telling her friends that she loves carrots more than anything, so whenever she and others talk about something carrot-related, she blushes and her face turns reddish-pink.
At first Rebecca did not make an animal sound like the other children. Instead she would giggle. But after the first season she started to use it less and began to squeak.
Not counting Aunts or Uncles, Rebecca's family has the biggest "main family", with 6 in the household (the second biggest being the zebra family).
Her favorite stuffed toy is a carrot with googly eyes. Its sound is, "Carrot, carrot!"
She blushes whenever she talks about carrots or when she is in the limelight.
