In this chapter Encyclopedia and Sally go to a lawn mower race to watch the lawn mowers go drive around. A teenager Mary Mullins was in the lead. And she crossed the finish line the winner. At the end Mary Mullins is very tired she hit two bumps, and her mower died. Ken, Larry, Bill, and the detectives go help Mary Mullins fix her mower. Ken found a nut a few yards away past the first bump and Larry found a bolt past the second bump. Bill went to go get wrenches. And sense Bill went to go get the wrenches, he put the nut and bolt back in place. Bill didn’t want Mary Mullins to win, so when he put the nut and bolt back in place he loosened them so that Mary Mullins couldn’t win. I like the part where Mary Mullins won the first race. She had the best mower so that’s how she won. Her mower was purple and green. And the strongest carburetor. The carburetor is where the gas stays. So, the strongest carburetor means that gas will never spill out. And it was the best one in the race. Everybody liked it. It was so nice that many people came closer to look. I do not like the part where Bill made Mary Mullins lose the second race. Bill is a little mean. He is one of Bugs meany’s gang the tigers. Mary Mullins finished last. There are seven mowers in the first race. And ten mowers in the second race. But Ken and Larry were both nice. They were one of Mary Mullin’s friends since they were three to seven years old. They always went to the same school. Ken’s cousin, Larry’s twin brother and Bill’s aunt were all competing too Mary Mullins was as well. I don’t know who the other people are, but I know that their competing which is fun in a lawn mower race.
