Manny Heffley

Manny Heffley is Greg Heffley's little brother. He calls Greg "Bubby" throughout the first book. During the play at Greg's school in book 1, Manny shouts "BUBBY!" and Greg deflects the embarrassment by saying "I think you dropped an apple, Bubby" to another person. He has an overbite and his teeth are far apart. According to Book 1, Manny is a fan of the television show Sesame Street, especially the "C is for Cookie"'' sketch.
