The Missing Bone Power Rangers DinoThunder : Season 1 Episode 17

While Dr. Oliver is stuck in ranger-form, he enlists the help of Kira to sort through his lab and throw away stuff he doesn't want. They find a bone that he doesn't want to talk about and locks it away. At the school, Dr. Oliver's position is temporarily filled by a surprising person who takes the students to the dinosaur museum. As the class is walking through the museum, Kira sees a Tyrano-drone and investigates. She is lead to a skull that hypnotizes her into doing whatever it wants, including stealing from a friend to make the creature whole.
