What this video covers
This video walks through the completed build of a pneumatic biohazard barrel Halloween prop. The effect uses an air-powered mechanism to lift or animate a barrel, enhanced with rope lights and an expanding-foam-and-latex creature head for a dramatic reveal. The finished piece combines practical pneumatics with atmospheric lighting and sculpted horror elements for a striking haunt installation.

Making a real Puppet Animatronic! #fnaf
Wicked Makers' Jaimie and Jay build a life-size animatronic version of The Puppet (Marionette) from Five Nights at Freddy's 2. The prop combines a foam-sculpted body wrapped in black velvet with a 3D-printed, painted mask sourced from a third-party sculptor. Two pneumatic systems power the scare: a scissor mechanism that launches the figure forward roughly three feet, and a chest-mounted pneumatic that thrusts its arms outward for the signature jumpscare effect.
We made a real DOGDAY Animatronic!
Wicked Makers' Jaimie and Jay build a full-scale pneumatic DogDay animatronic inspired by the legless, imprisoned character from Poppy Playtime Chapter 3. The build combines a steel frame powered by pneumatic mechanics (sourced from haunted attraction specialists Hallucinations Creations) with a custom 3D-printed and modeled head, a wire-and-foam body armature, and a shaggy fur exterior. Animation is driven by a prop controller from Purgatory Props, and the finished piece is set inside handmade theatrical flat jail cell walls. The result joins an expanding collection of Wicked Makers' video-game-inspired Halloween animatronics.
