First Do No Harm Pluto has been demoted and reclassified as a dwarf planet, but Vulture has big plans for it: "Vulture World," a grand amusement park filled with Vulture-themed rides and attractions. But first they'll need to terraform Pluto and make it more like Earth up there, by adding heat, water, oxygen and dirt. He dispatches Eagle, Robyn, Hawk and Raven to travel there and get to work on it. All is going as planned... until they hit an unexpected obstacle: the discovery of water! The #1 rule of space exploration: If there's any chance of life developing on a planet, or even a dwarf planet, they must leave it alone and return to Earth. Vulture is furious, and not to be denied. So he and Dodo fly to Pluto themselves to continue the cadets' work. But when Dodo accidentally terraforms Vulture's head, causing a flower to sprout there, all activity must cease - for good this time. Aaargh!!
