Astronaut Astro is a true scientist: he does everything according to plan, with structure and careful consideration. However, after setting up a base at the Shackleton Crater on the moon, he gets to know his new neighbor: The pink alien Blob, who already lives in the neighboring crater.

As a chaotic and curious living heap of slime, Blob touches, steals, imitates and plays with everything that Astro has. He especially loves Astro’s little helper robots and chases after them – and thoroughly disrupts Astro’s everyday life on the moon!
