Teen Groot Key Chain

Released in 2018, this Teen Groot Key Chain (set 5005244-1) was produced by the LEGO Group as a promotional tie-in for the Marvel Cinematic Universe film Avengers: Infinity War. The item features a molded plastic representation of the character in his adolescent stage, reflecting the mid-growth phase popularized in Guardians of the Galaxy Vol. 2 and subsequent ensemble films. It was designed to function as both a practical accessory and a small-scale collectible for fans of the Marvel franchise.

The design draws upon the specific visual characterization of Groot developed by Marvel Studios, emphasizing the character's spindly, wood-like aesthetic. By this period, LEGO had solidified its collaborative licensing relationship with Marvel, producing a wide range of minifigure-based accessories to accompany their standard building sets. While these key chains are mass-produced consumer goods rather than limited-run artistic pieces, they are well-regarded within the collecting community for their durability and faithful translation of complex digital character models into physical, pocket-sized forms.
