Freddie Harlahan is a boy in Greg Heffley's lunch group who sits at his lunch table. He appears in Hard Luck.[1]
Because of the Five Second Rule, Freddie once ate a piece of ham off of the floor thinking that Carl Dumas had dropped it, when the lunch meat was in fact from a previous lunch group or possibly even earlier. As a result, Freddie later got sick, ending up in the nurse's office for the rest of the day.
