It's the weekend, and best-friend dogs Schnozzer and Tatertoes decide to take an educational trip to the National Air and Space Museum. But when the dogs tumble into an active capsule in pursuit of a stray yo-yo, they soon launch themselves into outer space. Along their free-wheeling intergalactic journey, they experience the ups and downs of zero gravity, make contact with moon dwellers who want someone to to clean up the junk left behind by the Apollo missions, and even discover an asteroid heading directly for Earth!

It's up to Schnozzer and Tatertoes to save their planet. Will they return as Earth's greatest heroes, or will this bad dream go down in cosmic comic history?
