Mop Top bopped her billy goat's butt. The goat raced past the 
     window, and Mop Top grabbed the head. Then she galloped back down the 
     road. 
          The troll girls came leaping and bounding from the castle, 
     screaming and shrieking nasty troll words. They chased Mop Top till 
     they caught up. A troll girl reached for the head. 
          "No, you don't!" yelled Mop Top. She swung her wooden ladle. Bop! 
     That troll girl's head flew right off her shoulders, and the troll 
     girl had to run after it. 
          Mop Top kept swinging. Bop! Bop! Bop! Oh, those troll heads did 
     roll! All the troll girls had to chase their heads and leave Mop Top 
     alone. 
          By the time the troll girls had their heads on straight, Mop Top 
     had reached the ship and set sail. Then Mop Top took the calf's head 
     off her sister and gave her back her own head. 
          "You're wonderful!" said Fair Hair. 
          "You're right!" said Mop Top. 
          "Moo," said the calf's head.
