If you are a picky mom like me...i.e you DO NOT let your child watch "sponge bob" or "Scooby Doo" and you maybe even read Mothering Magazine, DO NOT get this book.
I didn't feel the jokes were appropriate, I guess I am a bit of a nerd about these things. It isn't funny to have a headless man poor beer/ale down the "hole" in his neck. They discussed murdering Shrek (hey leap pad, not age appropriate!!!!), and I didn't like to see "human" Shrek in chains fighting to get free (nor did my son).
They have "ugly" phrases that could have been more kid friendly, my son pointed out the ugly phrases, and snarled his nose at them saying "Mom, that was UGLY!".
I was dissappointed with this book, and I am taking mine back to the store.
I really like the leap frog system, even though I don't normally buy toys that require batteries...i.e the toys do something for the kid, instead I normally buy "old fashioned" natural toys where my son has to make the toys do stuff (blocks, leggos etc) BUT I REALLY love this system. It is a treat for my son to have an electronic toy so he really gets into Playing it and of course "accidently" learning.
I also didn't like the Hop on Pop leap book for similar reasons, even though the Dr. Suess part was great, the leap pad people added unneeded "ugly" phrases again that were just NOT age appropriate. Although I did like the minimal writing on most of the Dr. Suess pages.
I do like the regular "Leap" ones...moss lake etc, and the honey pot one with pooh bear.
Sorry to be so picky, if you are not picky you will probly like this book.
