A safety-conscious police officer has trouble getting the students of the local school to pay attention, until he brings in a police dog named Gloria, who energizes the performance.
This book contains examples of the following tropes:
- All Dogs Are Purebred: Gloria, the only dog in the book, is a German Shepherd.
- Amplified Animal Aptitude: Gloria can apparently understand Officer Buckle's safety tips and act them out in ways that the audience can understand and appreciate.
- False Cause: Officer Buckle doesn't realize that the audience isn't laughing at or clapping for him until he sees a tape of one of his and Gloria's safety talks on the news.
- Nap-Inducing Speak: The students of the Napville schools don't find Officer Buckle's pre-Gloria safety talks very interesting and tend to fall asleep while he's giving them.
- Pain-Powered Leap: Gloria leaps into the air to illustrate the safety tip to not leave thumbtacks on sitting surfaces.
- The Power of Friendship: Officer Buckle and Gloria cannot manage to get the safety tips across by themselves. Officer Buckle alone bores the audience so much they fall asleep, and Gloria alone just sits there, boring the audience until they fall asleep. With each other, however, they are a spectacular force for safety.
- Taught by Experience: Officer Buckle seems to learn at least some of the safety tips he tells the students by suffering the consequences of doing various things.
- 10-Minute Retirement: Officer Buckle refuses to come to the school for another safety talk after he's found out that Gloria's performances have been the reason people have been paying attention. Gloria gets dropped off at the school by herself, but without her partner, she just sits there and then falls asleep. Officer Buckle returns to safety-talk duty after the accident that follows (and a note from one of the students).
- Thumbtack on the Chair: A non-prank variation; Officer Buckle tells the students they shouldn't leave thumbtacks on places where they sit, remembering sitting on one that morning.
- Wing Ding Eyes: Gloria turns her eyes into x's to demonstrate why you shouldn't fly kites in a storm.
