Introducing Merrin and Pearl’s third audio CD case HBD: A Heart Pumping Adventure! During breakfast with her dad, Merrin is concerned about his eating habits and his heart. A few moments later, she and Pearl are riding on a red, pillowy, donut – shaped boat, floating on a red – colored sea and surrounded by hundreds of these grape – like things! Where are the girls and where are they headed?
The Human Body Detectives stories feature Merrin and Pearl, sisters who find they have the magical ability to enter different systems of the body to solve health mysteries. Through the girls’ action-packed adventures as Human Body Detectives, listeners learn how the various systems work and which foods best fuel each system. The accompanying workbook filled with games and puzzles reinforces what kids have learned from the audio cd and helps them further understand the importance of maintaining a healthy body.
