Irma, the iguana and Isaac, the indri, (inhabitants of an isolated island off of India) help Itsy, the inchworm, with an irritating itch in its innards. Ninth of a series of ABC alliterative stories, Itsy is Itchy emphasizes each letter "i" or "I" with a bold font. Children as well as ESL (English as a second language) students will enjoy the fun story while learning the many uses of the letter "I" and finding the hidden letter in each picture.
