Carlos is not just any worm. Carlos’s immune system is so strong that Moonie can bombard it with legions of aggressive invader organisms, and Carlos fends them off. But what’s truly remarkable about this worm is that while gobbling up intruders like a worthy ninja, it screeches out the famous first bars of Beethoven’s Fifth Symphony.
After twenty years of postponing her love life and toiling as a professor of immunology at Cal Tech, Moonie finally has a breakthrough. She has been studying the humoral and cellular system of an earthworm named Carlos for fifteen years.
