Paragraphs 1–2 of 5

In a cozy house on Maple Street, a small unicorn named Sparkle lived with her best friend, a red blood cell called Ruby. Sparkle had a shiny horn that glowed whenever she got excited. Ruby, however, was worried because a villain named Dr. Clot had been sneaking around the house. Dr. Clot wanted to block all the tubes and stop the heart from working. "We must stop him," Sparkle said. "If we don't, the whole body will suffer."

Sparkle and Ruby decided to follow Dr. Clot into the mysterious hallway that looked like a giant artery. The artery was a large tube that carried blood away from the heart. As they walked, Ruby explained, "The heart is a powerful pump that pushes blood around the body." Sparkle nodded, but she was a bit scared. Suddenly, they heard a loud noise. Dr. Clot was building a wall of sticky fat to block the artery. "You'll never stop me!" he laughed.
