When Mack & Moxy zoom off to HelpeeLand with Trooper Jax to save another Great Helpee, they meet a cool kid named Kendling Pop-Pop Jr. He's busy drafting an escape plan for his house in case there's a fire. As they're looking for the Great Helpee in the house, the Kendling's smoke detector beeps. Remembering how to stay safe, they ''get low and go.'' Meanwhile, Shelfish Sheldon scurries about to get the Great Helpee first so he can keep all its happiness for himself.
