Stinker's Return — Pamela F. Service

The little stinker is back! This sequel to Stinker from Space recounts the return of the alien who crash-landed on Earth and crawled from the wreckage to assume the form of the only available host -- a skunk. Nicknamed Stinker by his new friends Karen and Jonathan, the outer-space pilot was obliged to borrow a NASA shuttle to get back to his own planet.
Now Stinker's returned the shuttle but he still needs help. He's been charged with an urgent mission to find something uniquely "earthly" for a galactic ruler's collection. Even though Karen and Jonathan are still in trouble from last time, they can't refuse Stinker. The trio plunges headlong into a madcap quest through Washington, D.C., with the police and NASA officials hot on their trail. Their funny, fast-paced adventures will charm science fiction and fantasy lovers of all ages.
