The animals at the Zoo are worried. Someone is making a mess! Someone slept in elephant’s haystack, went potty and Ostrich’s sandbox, and scratched Giraffe’s favorite tree. This is a great story that reminds me of Goldilocks and the three bears. Children will be delighted to help guess who the culprit might be. The illustrations are colorful and each page is a question with a possible answer by the animals. The vocabulary is bold and children can help read along. It would make a great addition for any collection. ( )
