The Happy Problem Solvers: The Lost Key

By MD Antoine PhD(c) and Nathaniel M Antoine

Max and Leo can't find the key to their treehouse, and they fear they'll never be able to get back inside. But instead of panicking, they brainstorm creative solutions-like using a stick to unlock the door-and soon they're back in their favorite hideout.

A problem can often be solved with creative thinking and teamwork.
