The Boy Who Didn't Know He Was the Universe — Katie Cook

Book One in series. Benny Armstrong Jr. is a young budding astronomer who is very curious about the world he lives in, but what he doesn't realize is that his own body plays host to a variety of microscopic worlds. The inhabitants of these worlds, including the Floofs of Lintopolis, the Beats of Hipville, the Joymen of Lightville, the Buds of TasteTown, and the Zuzus of Jamaland, are no more aware of him than he is of them, but they have a profound effect on one another. In addition to these tiny worlds, Little Benny's every move is monitored by aliens from the Andromeda Galaxy, called Zetas, that like to wreak havoc in Little Benny's life. Between the school bully, Leo, and Little Benny's crush, Lora Lee, the Zetas never run out of mischievous scenarios. Little Benny just wants to understand his place in the universe, but little does he know-he is one.
