A young child loves to learn to count by tens. When the first four numbers, 10 - 20 - 30 - 40, add up to one hundred, the fast-growing size of the numbers takes on a new meaning. Add in a jungle with playful monkeys, who hear only the words they want, and a child's play hut that almost collapses, and an adventure begins.

When a sudden reversal of events puts the child in extreme danger, can the monkeys become heroes and save her? Reading the poem aloud, its rhythm adds a new dynamic to this playful and dramatic jungle adventure.
