I have read about 5 books to my Pet but it still hasn't showed up in my bookwarm achievements? It still says 0/25? Any help as to what I am doing wrong?

Also, in order to complete the plushie collector achievements do I have to place the plushies in my plushie collection? Shame to loose them that way, and not be able to sell them all after I finish the last tier :(

5 books? And you're trying to get the achievement for 25? Not sure if that's a typo but try getting 20 more books and then clicking the "books read" tab under the pet. And you do need to put the plushies in your collection for that achievement.

Ah! Clicking the books read tab under my pet did the trick! It now says 4/25 books read! That is what I was looking for. Thank you!

You're welcome :)
