Pigeon Boy

Pigeon Boy is a 2002 animated children's television show about a boy named Randolf, or Randy to his friends, whose town's pigeons transform him into a mysterious, comical, and lovable hero named Pigeon Boy. The pigeons spy on the town residents without being noticed very much. When they see something fishy is going on in the city, they summon Pigeon Boy. Only Randy's two best friends, Arthur and Chloe know about this hero side of him, but they don't tell him that they know; if Randy is aware that any one knows, he has vowed to give up the hero within him and never save his town again.
