Someone is making a great big mess at the zoo in this hilarious and delightful debut picture book. Can you find the culprit before the zoo animals' do in this gentle mystery for the youngest readers?

All the animals at the zoo are in a tizzy. Someone slept in Elephant's haystack, drank from Lion's bowl, went potty in Ostrich's sandbox (yuck!), and scratched Giraffe's favorite tree. Worst of all, someone tried to eat Goldie, the zoo's resident goldfish. Whoever it was has been leaving a suspicious trail of footprints behind. Is it a great big scary monster as the animals fear? Or is it something else entirely? Follow the clues on every page, and you just might be surprised to see who is behind this very messy situation.
