"Come on!" encouraged Crackers. "Race you to the top!"
Crackers set off with Boo running close behind. Boo was about halfway up when he began to run out of steam and bent over to catch his breath. When he looked up again he saw that Crackers, just a little bit ahead of him, was doing exactly the same!
"Phew!" exclaimed Boo, "that's really tiring."
"Maybe we shouldn't have run," suggested Crackers. "Let's get to the top a little more slowly."
Boo agreed but then had a sudden thought and started looking round desperately.
"Where's Scary?" he asked.
Crackers looked ahead of him. No Scary there! Then he looked across the hill. No Scary there either! Eventually he saw Scary very slowly climbing the hill below them, staring down at the ground all the time.
