"S.T.E.M. Strong" - 3-2-1 Blast off! On this mission to save another Great Helpee, the Heroes need Science, Technology, Engineering and Math. With Trooper Xolo, an aspiring engineer, Mack & Moxy head to HelpeeLand and come across a math-loving new friend named Munch Munch. But they're in for a big surprise when they discover that the Great Helpee is hatching atop a volcano covered in hot lava! Together they solve the problem by building a robot. Only one variable - Shelfish Sheldon is bounding up the hillside on a pogo-stick, perfectly poised to pounce and keep all the Great Helpee's happiness for himself. A celebrity cast including Hank Azaria (The Simpsons, Family Guy) and guest star Eva LaRue (CSI Miami, All My Children) helps the Heroes' mission in support of Citizen Schools, an education program that, through mentoring, helps thousands of middle school students across the US discover and achieve their dreams. "Get Up, Get Going" - On your mark, get set, go! Somewhere in HelpeeLand, a Great Helpee is hatching! Mack & Moxy jump into action with Trooper Lauren and bump into a friendly teenager named Blump who spends his time playing video games and eating candy bars. When asked to help the Heroes find the Great Helpee at the top of the mountain, Blump slumps and sighs. But once he breaks a sweat and gets into shape bike riding, hooping, and hiking up the hill, he reaps the rewards of exercise. As always, Shelfish Sheldon tries to beat them to the Great Helpee so he can keep all its happiness for himself. A celebrity cast including Hank Azaria (The Simpsons, Family Guy) and guest star Rachael Ray helps the Heroes in support of the President's Council on Fitness, Sports & Nutrition, whose mission is to engage, educate, and empower all Americans to adopt a healthy lifestyle that includes regular physical activity and good nutrition.
