It is the school holidays and Rebecca, Sarah and Mandy are in the park. Rebecca always thought that Sarah was her best friend, but now Sarah seems to prefer Mandy, who thinks Rebecca's a baby. When Rebecca wades into the witch's pond she is left alone, but not for long. She meets a very unusual new friend - a huge, warty toad! Glubbslyme is no ordinary toad. Hundreds of years old, he can talk and - best of all - he can work magic. Although toads are not Rebecca's favourite animals, he wants to be her friend and insists that she take him home with her. He teaches Rebecca how to fly and cast spells, but there is only one thing she really wants to learn. Can Glubbslyme help Rebecca to be best friends with Sarah again? A lighthearted tale of magic and friendship that will delight all young Jacqueline Wilson fans, read by Sandi Toksvig.
