Fisher Price Laugh and Learn: Learning Puppy Review

I like a lot a lot of things about this toy it has two modes - learning and musical, which are selected by pressing the button on its foot. The other foot, both hands, an ear, tummy and nose play sounds or songs when pressed. The puppy identifies body parts, colors and sings fun songs. It is very colorful, has a flashing bone on his shirt and volume control through a velcro seam on its back. My son finds it very easy to push the buttons. It teaches, body parts, colors and songs. And it has cute little sayings/ You push his nose, and he says "nose" push it again, he says "red nose", push it again, he says "a choo" then on another level, he sings "itsy bitsy spider", says achoo" then "got my nose!"  The down fall of the Fisher Price Laugh and Learn Learning Puppy is it has a hair trigger on some features and it is impossible to get it to work on others. Often it changes in the middle of a song - one of the feet usually triggering a change and he looks at me like "What happened?" This toy would be great with some major improvements.
