Well, this is a strange entry in the Clifford Universe. Emily Elizabeth is nowhere to be seen. Clifford's name does not appear in the text. The unnamed boy does look a bit like Emily Elizabeth, so I wondered if this is a cousin or half-brother or something.
There is also a long page filled with small print describing how the book should be used -- including tips to parents on how to read a book to a small child. I've never seen anything like that before. When I was a kid, everyone knew how to read aloud to others. It was like drinking water, blinking, or breathing. You didn't have to be taught -- you just did it.
I noticed that the edition of this book on the Internet Archive has been liberally scribbled in, presumably by a small child. Hmmm, didn't see that in the recommendations list by the Reading Specialist at Scholastic.
This book basically consists of Clifford imitating whatever the unnamed boy does. Clifford does a lot of imitating in many other Clifford books, such as Clifford's Kitten. That might be why he's so charming. That, and his clumsiness. And his unique looks. And his sense of humor.
