Jaxon's enthusiasm for the simplest things bubbles out of him, and ideas continually pop out of his very large brain. His delight in helping plant the garden with his family creates a magical learning opportunity, and he's well on his way to being as smart as his dad. But sometimes his zest needs to be clamped down, and his blurting embarrasses others.
When Dad shares a surprise for Mom, Jaxon discovers the secret monster: a naughty guy who lives inside him, waiting to blab as soon as his mouth opens. Jaxon swallows him down and tells him to be quiet inside his head, but will that monster listen? And what about the next time when Jaxon plots a prank on the ice cream man?
