Set #41775 Rainbow Unikitty: The character of Unikitty was a huge hit with the fans, so they decided to make a television series based on her and this Blind Bagged product was part of that offering. They called it Series 1, the chances of a Series 2 at this point are relatively slim. Unfortunately.

Rainbow Unikitty uses almost the same building technique from the original LEGO Movie, however they created a new part for the neck area to allow the 1x1 stud with clip on it first seen for the Daleks to plug into a hole. This new 1x3 reverse plate allows for a more stable connection of the head, well, now she doesn't come apart as easily, but her head is still pretty easy to remove.

Her printed detailing includes stars and hearts in numerous colours all over her tail, torso and face. I am not entirely sure what makes this a 'Rainbow', but it at least works out well enough as a new variant of Unikitty.

I think the real problem with this series is there are no unique parts, which makes this truly a blind purchase. Completing a set of 12 or just getting the Unikitty variants you want can be highly difficult. It took me a lot of purchases just to get all 12 items. To that end I suspect this is why LEGO chose not to make a Series 2. Overall I'd recommend this set for fans of Unikitty Variants or the overall look of the character. It's easy enough to purchase on the secondary market. Other folks may want to skip this sub-theme of Collectible Buildable Characters/Minifigures. Recommended for Fans.
