By a nine-year-old, for nine-year-olds (and younger kids), this is a frenetic tale of hapless crabs launched (both literally and metaphorically) into space to support a penguin's scheme to overthrow the rulers of Mars. A chaotic ride of puns, crabs, other animals, crazy names, a surprising number of food references, a plant pot-based prison break, and a villainous velociraptor defeated largely by vegetables.
