While Blaze and Pickle visit Crusher making meatballs at his restaurant, he accidentally spills a jar of grow spice on one of them, making it grow to giant size and trap himself and other trucks in it, so Blaze and Pickle become robots and work together to save them all.
Blaze and AJ are driving down a street in Axle City, when AJ smells something from a nearby restaurant. It is revealed that everyone is eating delicious meatballs and Pickle is serving them. After tasting them, Blaze and AJ decide to get some for themselves. They soon find the truck making the meatballs is Crusher, which surprises them. Crusher explains how he makes the meatballs so tasty, by adding 3 shakes of pepper, 2 shakes of salt, and one shake of the secret ingredient, grow spice, which could make the meatballs get bigger. When Pickle asks if he can try the spice, Crusher declines and says he's the only careful enough to handle it. More customers want more meatballs, and Blaze and Pickle bring out some more plates.
While they do that, Crusher proceeds to make his meatballs, singing in the process. But, by knocking into the table, the whole bottle of grow spice spills, making the current meatball he had been making get larger and larger, until it picked up Crusher and rolled out of the restaurant. Pickle sees Crusher is in trouble and attempts to stop the meatball on his own. But, the meatball is too big for him to stop, and it ends up making him fly through the air and land in a pile of road cones. Blaze and AJ ask him what happened, and they see Crusher trapped in the meatball. Pickle exclaimed he has to save Crusher, but he's way smaller than the meatball and asks Blaze what he should do. AJ says that the only way to stop the meatball is with 2 robots. Pickle tells Blaze that he could be one robot, and then, somebody else could be the 2nd one. When Blaze suggests Pickle be the other robot, Pickle says he's always dreamed about being a robot- ever since he's heard about the idea. Pickle agrees and Blaze and AJ build the robot transformation interface with help from the viewer, which Blaze and Pickle charge at to become robots. Pickle exclaims that he's got legs for running, arms for lifting and fingers for tickling. As he is tickling himself, Crusher screams for help. Pickle tells Crusher they are on their way. Blaze, AJ and Pickle say "Robot. . . Power!" before going forward. They race through Axle City as the Robot Power song played in the background.
