Yesterday I was (1) at the Dinosaur Museum. My friend Mike took (2) me there. First, we listened (3) to stories about dinosaurs. They lived (4) millions of years ago. They were (5) big and small. Some dinosaurs ate (6) leaves and grass. Some ate (7) small animals. Then we walked (8) around the museum and looked (9) at dinosaurs. Then I saw (10) the Tree Monsters. They were (11) noisy. Then Mike found (12) a white dinosaur tooth on the floor. No, it wasn't a tooth, it was (13) a pearl from your crown! I know! The Tree Monsters came (14) to the museum because they wanted (15) the pearl. Moldy and Rooty saw (16) the pearl too, but we were (17) faster than the monsters. I'm very happy! Now I have the first pearl!
