Good, cute talking book. Good audio
Format: Board book
This little book has pretty good audio and has lasted quite awhile. The story is cute, my little dude liked it, and it was well made. Thick board book so it's perfect for little hands.
(Amazon VIne people, please accept me into your ranks. I know this review wasn't as good, but IDK what else to really write, I got this for my nephew for Easter I think two years ago and it was destroyed after awhile intentionally. I don't have the greatest memory of it, but we kept the speaker part after because he liked it before we finally just got rid of it while cleaning...sorry lil dude if you ever come across this review, I'll get you a new one if you're that passionate about it)

Great for small kids
Format: Board book
Love this book. Easy for the kids to turn the cardboard pages, and the sound buttons are easy to push. Bought for my 2 year old grandson’s birthday, but 3 year old cousin keeps trying to steal it.
