An uplifting tale about the power of friendship, finding your place in the world, and realising your dreams while remaining true to who you are.

Tumbledown is a little demolition truck growing up in a loving family. His parents go to work every day demolishing buildings with their big wrecking balls. But soft-hearted Tumbledown doesn’t like to destroy. He’d rather build things. He dreams of being a cement mixer.

When Tumbledown cries, his wrecking ball swings out and destroys everything it touches. When Tumbledown laughs, his wrecking ball swings out and destroys everything it touches. His soft heart can’t skip a beat without leaving a trail of destruction. At school other students laugh at him, but still he won’t let go of his dream. When Tumbledown makes friends with a feisty troop of metal springs, they hatch a plan to save him from himself. They fan out over his wrecking ball and every time it swings they do their best to absorb the shock. The day comes when the worn-out springs turn to the Wise Old Crane for help.

Tumbledown can never be a cement mixer, but maybe there are other ways, better suited to his nature. After some search, the Wise Old Crane finds a new job for Tumbledown at a construction site using his wrecking ball to smooth out the cement on the ground. It’s hard work but Tumbledown is finally happy, and he grows stronger and more skillful with every passing day.
