Lulu and the Brontosaurus

It's Lulu's birthday and she's decided she'd like a pet brontosaurus as a present. When Lulu's parents tell her that's not possible, Lulu gets very upset. She does not like it when things don't go her way. So she takes matters into her own hands and storms off into the forest to find herself a new pet, all the way singing: I'm gonna, I'm gonna, I'm gonna, gonna, get

a bronto-bronto-bronto-bronto-saurus for a pet In the forest Lulu encounters a number of animals; a snake, a tiger, a bear, all of whom don't particularly impress her. And then she finds him...a beautiful, long-necked, gentle, graceful brontosaurus. And he completely agrees with Lulu that having a pet would be a wonderful thing, indeed Lulu thinks she's gotten her birthday wish at last. Until she realizes that Mr. Brontosaurus thinks that she would make an ideal pet for him How will Lulu ever get out of this sticky situation without throwing a fit (Mr. B does not respond well to those), or using force (Mr. B is much to tall to bonk on the head with her suitcase), or smushing her pickle sandwich?
