I can tell you like these sets, Blue.

I'm not the only one.
So I have these two sets:
41050 Ariel's Amazing Treasures - it contains Flounder!! This is epic for those of us wanting other fish for our water scenes. It has the new plant pieces which are really really nice. (I need like 1000 of these). It has the cactus plant piece in a bright green. Not to mention a tile with sheet music printed on it. Plus a lot of nice little flower pieces. It is a nice little set. And I'm not just saying that because I want to be a Disney Princess.
41053 Cinderella's Dream Carriage - Now normally I will tell you, I am not big on carriages. But I do like this one. It is a different build. It has lovely colors. And it is sturdy. The set has pink heart gems!!!!! And a treasure chest in that medium lavender of the Friends line. The carriage wheels are...really decorative but that would make amazing wheels for a really rich King's carriage. There is a mushroom and two pumpkins. And two of the fancy new 1x1 round with the dome on top.
Overall, they were good solid builds full of amazing girly girl happiness and delight. And the parts are well worth buying them. Even if you can't see yourself buying them for a castle build, trust me, you may end up using them in one way or the other.
I shall be buying the whole line. So I'm sure if I remember, I will update you on what I am finding...just so to tempt you to buy these. Or your Mom to want them, or even your Gramma...because I already tempted a few women in the TRU I was at, including a couple of Gramma's. Hey! Sharing the LEGO loving is always a good thing. And just think...if you can get your Mom or Gramma to love the LEGO...they could share the loving back with you!
*edit*
I have found two more!!
41502 Ariel's Magic Kiss - There are lovely pieces in this set. I'm not so sure there is much castle parts in it other than the gold domed 1x1 rounds. There are 3 of the new plant piece and 1 of the new heart gems. The "catcus" piece is in the bright green. Overall it is a great build and it has FOOD! And a pink rowboat but I doubt that has any fascination to many here.
41504 - Rapunzel's Creativity Tower - Now this one has a lot of annoying large round pieces. I'm not a fan of the big wall pieces..AT ALL. But there is PASCAL!!!! If you have watched Tangled then you have to just love that he exists in brick form. There are lots of details like paintbrushes and the like. Way too many stickers that I didn't use because I am anti-sticker. Lots of plants. Over all a fun build, with a lot of pink and purple. Yay pink and purple.
