CatStronauts: Robot Rescue: 07/19/18
CatStronauts: Robot Rescue by Drew Brockington is the fourth book in the graphic novel series. The book opens with Blanket's robot, Cat-Stro-Bot drilling an ice core on Europa. There's an accident and communication is lost.
The remainder of the book is about how the CatStronauts try to rescue Cat-Stro-Bot. How they go about it might give parents pause in that they don't follow rules and they steal (borrow) a spaceship to mount their rescue. Their reasoning is one of loyalty to a colleague and the question of Cat-Stro-Bot's sentience and value as an individual.
To hide their absence, the CatStronauts use other robots painted liked themselves and programed to act like themselves. There are some gags about first how much better they are at being CatStronauts than the actual cats. Then later when they short out, there are gags about how much worse they can be.
The payoff though comes in the furthering of science and technology while rescuing a friend. A new space ship is tested out (and it happens to look a great deal like the ship from 2001: A Space Odyssey. The Europa experiment is a success. Cat-Stro-Bot is rescued.
All in all it was a fun read but it wasn't as tightly woven a plot as previous ones were.
