Achoo! Rocket's Grandma is in bed with a bad cold. Rocket is on his way to Poland to visit her, bringing a huge pot of yummy Rocket Soup to help Grandma Rocket feel better. But as our heroic red Rocket travels through the dark forest, danger lurks. No, not a wolf. Much worse. It's Big Jet! Big Jet craves Rocket Soup and snatches the bowl from Rocket. And so, Rocket and the team set off on a mission to catch Big Jet and retrieve the soup. But it's not going to be easy. Big Jet has many crafty disguises. And when the team finally gets the soup and presents it to Grandma Rocket, they're alarmed to see that Grandma Rocket doesn't look quite herself today. Yikes! It's Big Jet in another disguise! In the end, though, Big Jet gets his comic comeuppance. And Grandma Rocket enjoys not just the soup but a visit from her favorite grandson Rocket, and that, in the end, is the best medicine of all.
