LEGO Seasonal 40815 Birthday Party Cake

LEGO set 40815, Birthday Party Cake, depicts a decorative birthday cake with candles, icing and colorful flowers.

Birthday Party Cake is part of the Seasonal theme, a category used for models tied to celebrations, occasions and decorative display. The subject is not a character scene, but a brick built birthday cake intended to stand on its own as a festive object.

The build uses 219 pieces to create the cake, icing, colorful flowers and candles.

It suits builders looking for a small display model, a party decoration or an addition to a Seasonal collection. Compared with other sets in the theme, it has a broad occasion based subject, since a birthday is personal rather than tied to a specific public holiday.
