Blue, Barry, and Pancakes are friends. Sometimes they love to play together, but one day, Blue and Barry just want a quiet day to themselves. Unfortunately for them, Pancakes has other ideas - ginormous, inflatable, intergalactic-adventure-sized ideas! Soon enough, Blue's and Barry's dream of a quiet day has become a squeaky nightmare. They, along with Pancakes, find themselves stranded on a planet that's populated by living balloons called Balloonians. And if the gang wants to get home, they'll have to work together to overcome the biggest, meanest, and scariest Balloonian of them all - Balloon Kong!
