Dinosaurs are back, and on the loose! It's up to D-Bot Squad to catch them. Hunter is reeling from the effects of the dino-fart but just before he collapses he manages to call for help. Meanwhile, the stegosaurus (the steg) crushes part of his d-bot and looks set to crush the rest. Charlie arrives just in time and rescues him by luring the steg away with its favourite plant. While Hunter repairs his d-bot, Charlie distracts the steg, until Hunter joins her to battle the it. They teleport the steg safely home, only to find an argentinosaurus approaching ... with a third D-Bot Squad member in its clutches!
