This is a mostly 2-dimensional build that looks amazing as a display piece on a shelf. Fortunately, it's not without its charming interactive elements, like a crank handle that makes Yoshi run with Mario on his back, and a dial that makes Yoshi's tongue pop in and out.Despite its simple design, this is a fairly challenging build that involves small bricks and technical pieces like rubber bands, hinges, and ball joints. LEGO recommends it for builders ages 18 and up. The end result is more than worth it, though.
