Happiness Party♪.The girls are all asked to help create designs for a line of "Happiness Toys" by popular toymaker Dandai. After the girls meet with some children representing their target audience, the project designer Nakaya decides to go with a line of Aikatsu Dolls that children can play dress up with. As the girls work to come up with ideas for the commercial, Nakaya works with the top designers to get some prototype dolls made, but struggles to get a hold Asuka to approve designs of Madoka's doll, which they soon discover is due to her dedication to get several Angely Bears ready for Christmas. After managing to get approval on Madoka's doll, Nakaya asks Asuka to allow Angely Bear to be included in the commercial, while Tsubasa makes his own adjustments to Akari's doll.
