Oliver and Troll face the biggest, meanest, grumpiest troll of all!


It was awesome. Grumbug is so big and green and he can drink a river dry!

This book is very funny and when Dolly gets lost they make a giant cake for the Grumbug when they find her.

Grumbug was a bit funny. He ate a big cake and said Yum at the end of the book.
