This wonderful book is natural science - in this case, about desert animals - with a flair. A boy walks up to an impressive saguaro cactus and wonders who could be living on this arid ground? As night falls, he walks away. And then the place comes alive! A haven for creatures in a waterless land. The entertaining, repetitive rhyme is an attention-grabbing read-aloud that culminates in successful learning. Field Notes at the end of the book describe the animals in detail and include an unusual fact.
