What this video covers
Wicked Makers' Jaimie and Jay build a full animatronic version of Bill Cipher, the iconic triangle demon from Disney's Gravity Falls. The build combines XPS foam carving, metal frame construction, 3D-printed eye mechanics, and DryLok stone texturing before being painted and detailed with signature accessories. Micro servos driven by the free Bottango software bring Bill to life — making him look around, blink, float, and deliver custom voice lines recorded by Jay. The result is a highly characterful display-ready animatronic that fans of the show and Halloween prop builders alike will find impressive.
Key takeaways
- ◆Bill Cipher's body was carved from XPS foam, texturized with DryLok for a stone look, then painted and detailed with hat and bowtie
- ◆A welded metal base and frame provide a sturdy mount for all servo and electronics components
- ◆The eye and eyelid were 3D printed, with the eye mechanism available separately via the creators' Patreon
- ◆Free animation software Bottango was used to program all movements, including looking, blinking, and floating
- ◆Custom voice lines recorded by one of the creators give the animatronic personality and interactivity

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.

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.
