ISBN 0934323011 - Not a fan of Ruxpin here, so take my critique with that in mind. I also no longer have the audio that went with this book, and have blocked it from my memory, so I can only comment on the book.
The colored text on top of dark and sometimes busy graphics make reading the badly written poetry (ok, lyrics) a chore. Not every page has that problem, but the ones that don't still suffer from horrible efforts at stringing together rhymes. The illustrations aren't bad, but again, a little busy for the eyes of one trying to drift off to sleep.
All in all, I wouldn't buy the book and can't give away the 2 copies I have. My dislike of poor Teddy might be colored by a memory of a singing Teddy Ruxpin doll that once tried to bite off my child's fingers, but that memory along with this book make me wonder what in the world these folks are thinking in their "Worlds of Wonder". Sing your child to sleep, no matter how bad your voice, and pass up Teddy this time - they'll have much more pleasant memories of that than of this book.
