While enjoying autumn weather and activities, Mr. Putter, realizing how much he misses going to school, takes his cat Tabby, their adventurous neighbor, Mrs. Teaberry, and her cake-loving dog Zeke to "Show and Tell.".
More humorous episodes from the classroom on the thirtieth floor of Wayside School, where students learn to tango, face the cafeteria's dreaded mushroom surprise, and study a hobo during show-and-tell.
Henry was the only youngster in the class who was afraid to participate in "show and tell." But one day his teacher gave him a hint and Henry brought his pet lizard to school and it promptly escaped. Things changed for Henry after that experience.
