When Rebecca wades into the witch's pond after a row with her best friend Sarah, she meets a very unusual new friend - a huge, warty toad! And Glubbslyme is no ordinary toad. Hundreds of years old, he can talk and - best of all - he can work magic. They have alot of fun, including attacking with an army of slugs and flying, but Rebbeca can't help wondering: Maybe, just maybe, he can help Rebecca be best friends with Sarah again...?
Only the front cover was illustrated by Nick Sharratt, who usually illustrates Jacqueline Wilson's books, the inside illustrations were instead done by Jane Cope.
