Howie, a curious 5-year old boy, and his best friend Baboo ask ALOT of questions. Through creative play, their imaginations invent wondrous animated worlds that prompt real-world questions: How does a fish breathe underwater? How does a tornado happen? How do astronauts float in Space? How do bees make honey? Why are flowers different colours? Where does the water go when you flush? With the help of real-life kids who offer their (sometimes hilarious) responses, Howie and Baboo venture out from their secret treehouse headquarters into the real world to meet Experts who help them find the answers to their questions.
