Thomas and the Hide-and-Seek Animals is a twenty-four page book first published in 1991 by William Heinemann Ltd and was subsequently re-printed in 1993. The book was unavailable and out of print for a number of years, until a new version of the book with updated graphics was published by Random House Books in September 2007.
A new zoo is opening on Sodor and James is bringing the animals. But the monkeys take the keys and unlock some of the doors. The animals were soon loose and running around the yard. Thomas and his friends round up all the animals, just in time for the opening of the zoo.
- On each of the flaps, each animal has a different saying.
- All of the pages have flaps, except for one. On the only page that doesn't have a flap, all the animals are rounded up. But Thomas' driver along with a few other men are lined up pushing the elephant because he gotten stuck in the truck door. The baby elephant is at the back of the line helping them push. Thomas, Sir Topham Hatt, the passengers and the other animals watch as the line of men and the baby elephant push the elephant.
