The PAW Patrol pups transform into The Mighty Pups after a meteor crash lands in Adventure City. For Skye, the smallest member of the team, her new powers are a dream come true, but things take a turn for the worse when the pups’ arch-rival Humdinger breaks out of jail and teams up with a mad scientist to steal the superpowers for the two villains. With The Fate of Adventure City hanging in the Balance, the Mighty Pups have to stop the Supervillains before it is too late, and Skye will need to learn that even the smallest Pup can make the Biggest Difference.
