What Makes this set WOW?

Unique Minifigure Molds: The set offers unique, dedicated head molds for Elmo, Cookie Monster, Bert and Ernie, and a special rubber body mold for Big Bird.

Nostalgic details and references (Easter Eggs): The interiors contain numerous references to the series, including: a portrait of Bert and Ernie, Dorothy the fish in Elmo's bedroom and a nest with Radar the bear.

Interactive Trash Can: A specially designed mechanism allows you to extend and hide the Oscar the Grouch figure, which allows you to faithfully recreate iconic scenes with his participation.
