Junie B. Jones, hilarious heroine of more than a dozen well-loved books, is mortally afraid of ponies. An imprudent babysitter once allowed her to watch a cable TV show called When Ponies Attack, so a trip to a farm seems like the ultimate in reckless endangerment. Never mind the roosters, which, according to her classmate, Meanie Jim, can peck your head to a nub. It takes some pretty fast talking by Junie's parents, teacher, and the farmer himself to get Junie to participate in the field trip, where she has a surprisingly good time. Until she bonds with Peep, a fluffy little chick, only to discover, to her horror, that Peep's destiny is to become a rooster.
