"Buckle Up for Safety" - Road trip! It's time to find another Great Helpee! As Mack & Moxy head out of Headquarters with Trooper Sade they wind up on the wrong side of HelpeeLand. The Heroes luckily get a ride from Jalopy, an open-aired mini-van who is toting around Chuckling, an adorable duckling. As they sit in their proper car seats and buckle up for safety, they hit the road heading to the Great Helpee. But Shelfish is zooming along ahead of them, confident that this time he'll keep all its happiness for himself! A celebrity cast including Hank Azaria (The Simpsons, Family Guy) helps the Heroes' mission in support of the National Highway Traffic Safety Administration, where motor vehicle and highway safety is the number one priority since 1970. "Ready, Set, Hike!" - Adventure awaits! As a Great Helpee is ready to hatch in HelpeeLand National Park, Mack & Moxy head out with Trooper Tigran. They're welcomed by Ranger Rosey, an extroverted outdoor enthusiast who is delighted to introduce them to the wonders of nature. Along the way they breathe in the fresh air, explore the terrain, discover different types of plants, learn about the park's history, and take photos to share, inspiring others to enjoy the majestic lands. But sharing doesn't work for Shelfish Sheldon, who scrambles to the Great Helpee, set on keeping all its 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 the National Park Foundation, a legacy focusing on safeguarding our natural heritage in over 400 national parks and inspiring lifelong engagement for the next generation of park stewards.
