One hop. Two hop. Three hop. Four . . . There's music rising up from the jungle floor. So readers shouldn’t be surprised to encounter slap-clapping rhythms and sort-a-snorty songs that cause their feet to start tapping to the Jungle Beat. When a reader inserts his hand into the puppet element on the back of this book, he’ll be placing it into the mouth of every jungle creature featured. Launch date: September 2007.
