This LEGO Wednesday Black Dahlia Flower set (76784) lets builders ages 9 and up explore Wednesday's world by constructing an elegant black dahlia display that transforms into a hidden Nevermore classroom. When you lift the mysterious flower, it unlocks the conservatory vase to reveal Professor Thornhill’s secret classroom, complete with movable furniture and accessories. The set includes Wednesday and Thornhill minidolls for recreating scenes from the show or imagining new adventures. After play, the model makes a unique piece of bedroom decor. It’s a thoughtful gift for birthdays or Halloween, appealing to boys, girls, and fans who enjoy creative building and Wednesday Addams stories. With 358 pieces, the finished greenhouse model stands over 9 inches (23 cm) high, 4 inches (10 cm) wide, and 3.5 inches (9 cm) deep when closed. For added help, the LEGO Builder app offers 3D viewing tools and step-by-step digital instructions.
