Primula is a little bigger than the average Nendoroid. Her head is a bit bigger, as well as the rest of her body. She does actually talk, which means her head needs to have enough space to possess a battery. The fact that she is so big does make her a little difficult to stand up even with the use of the stand.
Her pig tails move as well as all normal Nendoroid parts. She comes with the three adorable kittens shown as well as the stand. I believe she is an earlier Nendoroid given the style of her stand- which to be honest I'm not the biggest fan of..
Overall I think she's a really cute addition to my collection! She's definitely different than most of the other Nendoroids not only in size but also in the fact that she speaks.
I don't know that I'd recommend her though unless you can get her for cheap. Lots of people seem to like to ask over $100 for her, and you have to consider all she does when looking at the price. Is she rare? Yes. Is she "deluxe"? Yes. However, she does not come with any extra faces, arms, or legs. She comes with exactly what is seen here and that is all.
If you're the type of person that likes to simply display your Nendoroids (with changing out the faces and parts every now and again) and won't be pressing the button to make her speak or playing the game, she may not be the Nendoroid for you.
I have tried and tried to find information on the Shuffle game, but so far the only thing I've been able to see is pictures. Thankfully I know a little Japanese so I should be able to translate somewhat efficiently. From looking at the pictures on the box it looks like you can decorate Primula's bedroom or house and play as her in the computer game. You should be able to dress her up as well. As far as other options for gameplay go, I'm not sure as of yet.
