Rowley Jefferson

Rowley Jefferson is Greg Heffley's best friend by far. Even though that Greg has done some bad things to Rowley, like breaking his hand and big toe, and getting him in trouble for something he didn't do, they still remain friends. In the first book, Rowley ate the cheese, but no one knew. Besides that, Rowley is often nice to everyone and he always has his mouth open. Rowley has very little will power, since Greg can convince him to do almost anything that he tells Rowley to do.

Rowley is very immature, as heavily implied in Diary of a Wimpy Kid: Rodrick Rules. There, he gets a whole bunch of kiddie toys and a girlish diary - however, he's happy about it. This shows that Rowley is immature. Also, in Diary of a Wimpy Kid: Dog Days, he ends up taking the chocolate-covered raisins over a trip to the grand championship of Twisted Wizard 2. In Diary of a Wimpy Kid: Rodrick Rules,Greg looks at Rowley's "Sweet Secrets Diary", which he got beforehand in the book, and finds out he hardly puts anything cool in it; he doesn't even put Greg's NAME in it. Which makes Greg wonder why he's even friends with him in the first place. He is played by Robert Capron in the movie.

Appearance
Rowley appears to be wider than Greg. He has 7 strands of hair, sticking downwards in a curved way. Rowley never has appeared with his mouth closed, leaving him with an open happy face, or sad happy face.

Interests
Rowley has strange interests, for his age and gender. Rowley is hooked into a singer, Joshie, which Greg stated was for 6 year old girls. Rowley, is said in the first book that he likes a single boxed comic, "Li'l Cutie."
