Zooman Sam (Unabridged‪)‬

It's Future Job Day at Sam's school, and Sam knows exactly what he wants to be when he grows up-a zookeeper, just like Zookeeper Jake in his favorite picture book. His mother and big sister, Anastasia, help Sam create a memorable costume-so memorable that Sam insists on wearing it long after Future Job Day has passed and the rest of his classmates are back in their regular clothes.
Encouraged by Mrs. Bennett, his teacher, Sam embarks on a lengthy project to teach his preschool class about a zookeeper's responsibilities, and along the way learns just how difficult a job teaching is. As always, the patient and loving Krupnik family stands by as Anastasia's irrepressible little brother struggles with a set of nearly impossible goals. Children will delight in this latest story featuring the precocious and irresistible Sam.
