Zizzer Zazzer Zuzz by the jc monster

The Zizzer-Zazzer-Zuzz is a strange creature in the forest whom Ichabod and Izzy meet at the end of the book of Dr. Seuss's ABC. He tells the viewers in the book/video/Living Books version that he begins with the letter "Z" as everyone can plainly see.

In the Living Books version of this book, they believe he has escaped from the zoo.
