Does anyone know if the "All of the Plushies" achievement also includes the Cash Shop plushies?

Yes, you need all the Cash Shop plushies as well

Thanks for answering! Now at least I know I'll probably never be able to get that achievement!

You're welcome! It's definitely one of those achievements I'm never gonna bother with.

- I wish I could, but I need my CSC for impulsive CW shopping sprees. XD
