Fregley

Fregley is a widely unpopular student at Greg's school, and is a minor antagonist in the series. Like Rowley, he has appeared many times with his mouth open, much more often than most of the characters.

Personality
Fregley tends to be illusive and over-confident as his character in the series, always hanging in his front yard doing a wide range of silly activities, such as stabbing a kite with a stick, talking to Greg about a lot of repulsive topics, such as his hygiene issues and his scab, much to Greg's dismay. In Diary of a Wimpy Kid, it is revealed that he shouts "Juice, juice!" when he needs to use the restroom; teachers often view this literally and often end up giving him juice out of frustration.

Appearance
Fregley is illustrated with glasses, a wide-open mouth, a black shirt and a scarf in Greg's journals.

Greg Heffley
Greg emphatically is not at all fond of Fregley, although Fregley seems to think that Greg is his friend. Fregley offers to talk to Greg about various strange topics, and offers to play absurd games with him, such as "Diaper Whip," one of which totally makes Greg unhappy. In Dog Days, Susan invites him to Greg's house, only to end up in a huge conflict. Greg notes down "I think his parents own an electrical fence or something."
