Some could find it inappropriate for kids due to the content (although buying a book called “I need a new butt” should be an indicator that it is about butts…).
The books are also still educational. Our kindergartener has been learning about letter sounds and rhyming so these books have been fantastic for that. Every part of each book is constant rhyming making it great practice for kids to hear it as well as to read it (for those kids old enough to read).
The only downside (and reason for one docked star) is that the sound effects really do not have any purpose other than making everyone laugh. However there is no prompt for sounds in any of the books and the button is difficult to push while reading. So then it becomes just a barrage of fart noises going off while trying to read. Thankfully it has an off button!
These books overall are entertaining for all ages to read and has been a go to gift for parties.
