A little girl finds a lost dinosaur baby roaming the halls of a museum and is determined to give it a home in this sweet and charming picture book.

Penny feels certain that something is following her down the hall as she walks with her class through the Natural History Museum. She looks-nothing. She looks again-still nothing. She looks one more time and spies a verrrrry long neck and a verrrrry long tail on something that looks suspiciously like a baby brontosaurus!

Penny might be only five, but she knows dinosaurs are extinct. And yet, one seems to be following her. The little dino and Penny spend time together all over the museum, and when Penny doesn't see a giant adult dinosaur lumbering around, she realizes Pip-as she's named him-must be on his own. The only thing to do is to feed him some snacks and take him home with her...if she can figure out how.
