Rebecca looks taller than Rachel and Kirsty. She has long blonde hair, much like Danielle's and she wore a jumper and a skirt.
When Rachel and Kirsty were unable to get the daisy petal, Rebecca saw what was going on and lent them a hand. As thanks, she was given a magic daisy chain, and promised to never forget the fairies or her friends. She is the only human besides Rachel and Kirsty to know about the fairies, goblins, Jack Frost, and Fairyland. She has a family.
The cat on her sweater looks similar to Marie, a character from the Disney movie The Aristocats.
