The Cosmic Zookeeper is searching for twenty-six rare animals to complete his Cosmic Zoo! Then he will have every known animal from the planets of the Binary System, including the rarest creature of them all. Captain Zedess and the crew of the Z Ship arrive to locate the animals in a wild adventure across planets teeming with strange creatures.

Come with them to explore ICEBALL- the frozen planet, BONEDRY- a world where the oceans have gone and all the fish have to walk or fly. But the Animal Freedom League are also on the job, and doing their best to foil the plans of the Zookeeper. This is another amazing puzzle book by Stephen Stanley and is filled with colorful double page spreads of all the planets plus the Cosmic Zoo.

In the end will the Cosmic Zookeeper actually find any animals at all? There are questions and answers that will keep you occupied for hours.
