This book is second in the series about a budding young inventor and his adventures in Washington DC. Just like the last book, this is a positive story filled with supportive and caring friends, family, and neighbors. Readers will relate to Melonhead's tendency to accidentally get in trouble. His parents give him consequences for his bad choices. One such consequence is to help his neighbor with her housework, and they become friends after he learns she was a pilot and her husband was a famous entomologist. Readers will learn a few things about botany, including how to make their own floating fountain. Hard work, creativity, and good deeds are celebrated. Language is mild (f-rt).
