Irving Du Bois

Irving is a character from Phineas and Ferb. He is a boy who is Phineas and Ferb's self-proclaimed biggest fan. He always carries a scrapbook that he filled with images and souvenirs from Phineas and Ferb's Big Ideas with him (such as the roller coaster, the chariot race, and the boys with some sort of soup, most likely from the time they created Chez Platypus). He has pictures and stories of the gang ever since day one. He even has a lock of Ferb's hair. He apparently was with them the whole day but had gone unnoticed because his horoscope says he's "the background type." He likes to join in on their escapades regardless of whether or not he was invited (and he usually wasn't). Phineas, Ferb, and their friends, as a result, do not seem to think of Irving as an acceptable member of their group.
