Flying saucers! Meteor showers! Poison gas! Watch out, captain Invincible! Side by side with his loyal space-dog, Comet, the fearless captain battles his way through outer space, relying on his knowledge of three-dimensional shapes, including cones, cubes, cylinders, and spheres, to make it safely back to Earth.
