Real YARNABY Animatronic! 🧶😱 #poppyplaytime

Wicked Makers' Jay and Jaimie construct a full animatronic version of Yarnaby from the horror game Poppy Playtime, built from steel and driven by pneumatics. The build goes beyond aesthetics — the team stress-tests the animatronic's jaw mechanism using a ballistic gel arm to see whether it could realistically bite through a limb. The video blends behind-the-scenes fabrication footage with chaotic prop-testing in classic Wicked Makers style. It sits alongside their broader catalog of mascot-horror animatronics inspired by FNAF, Poppy Playtime, and similar franchises.
