Four Leaf Otis

Otis finds a giant chicken egg and decides to hatch it so they can have a fifth for polo. Only the giant chicken turns out to be a dinosaur! The animals immediately want to get rid of it, but Otis has paternal feelings and begs the animals to give him a chance. They relent, but the dinosaur quickly grows 1000 times its size and falls in love with Mrs. Beady!
