Manny Heffley
Manuel "Manny" Heffley is the younger brother of Greg and Rodrick Heffley; a ridiculously-pampered, annoying, obnoxious, Spoiled-rotten toddler who is constantly being doted on by his mother. He has a great number of demands and requests, and will throw temper tantrums if these wishes are not fulfilled and he is extremely self-absorbed in spite of his young age. Among Manny's most well-known character hallmarks are his refusal to be toilet-trained and his complete inability of entering a nursery school in which he can remain. Despite his very young age, Manny has shown signs of actually possessing more intelligence than he seems to; he managed to keep the electricity turned off in every room of the house with the exception of his own in "Cabin Fever" and it was in this same book that he successfully managed to change the password to Greg's account on a gaming website net krittez He also has been shown to frequently damage the property of his older brother Greg, as seen in a number of books, and the excessive coddling that he receives from his parents infuriates Greg deeply. In Cabin Fever, it was found that when Manny is scared, he hides in his sock drawer. He also takes advantage of his spoiltness, as he often teases Greg when he gets a new toy that Greg didn't get. He also has red hair unlike his brothers. Manny is also quoted as having imaginary friends in the book "The Third Wheel" and accuses his imaginary friends responsible for the mischief caused by himself. One of his imaginary friend's name is Johnny Cheddar, and Greg calls him the "trouble maker of the pack." Manny threw a tantrum when he supposedly left Charles Tribble (another imaginary friend) in the grocery store. Greg thinks Manny makes imaginary friends to get extra dessert.
