We made a real YARNABY Animatronic (that can eat people)

What this video covers
Wicked Makers duo Jay and Jaimie build a full-scale animatronic version of Yarnaby from the horror video game Poppy Playtime, engineering it with steel and pneumatics to deliver a genuinely powerful bite. The build is documented from concept through construction, culminating in a dramatic ballistic gel arm test to measure whether the finished prop could realistically 'eat' a person. The project blends character-accurate prop replica work with serious mechanical engineering, resulting in a haunted-house-worthy centerpiece. It's chaotic, messy, and deeply impressive in equal measure.
Key takeaways
- ◆Yarnaby is recreated as a functional animatronic using steel framing and pneumatic actuation, not just a static display piece
- ◆The jaw mechanism is powerful enough to visibly destroy a ballistic gel arm in the bite-force test
- ◆The video includes a behind-the-scenes breakdown of the full build process with prop-making insights
- ◆Collaborators from the prop and animatronic community contributed to the project
- ◆The channel has a broader catalog of mascot-horror animatronics including FNAF and The Walten Files builds
Who this is for
Intermediate-to-advanced prop makers and Halloween enthusiasts who want to see how a mechanically functional, character-accurate horror animatronic is engineered from the ground up.
Materials mentioned
- • steel
- • ballistic gel
- • pneumatics
⚠ Safety notes
Pneumatic and steel fabrication components are involved; proper metal working and pneumatic safety practices should be followed. Ballistic gel testing is used to demonstrate significant mechanical bite force — keep clear of moving jaw mechanisms during operation.

We made a real DOGDAY Animatronic! #poppyplaytime
Wicked Makers' Jaimie and Jay build a full animatronic version of Dogday, the unsettling canine character from Poppy Playtime Chapter 3, entirely from scratch. The build combines 3D printing with pneumatic mechanisms to bring the character to life with realistic movement. The short-form video offers a high-level showcase of the completed prop and build process.
REAL CatNap Animatronic! #catnap #poppyplaytime #shorts
Wicked Makers' Jaimie and Jay build a fully functioning CatNap animatronic from scratch, bringing the popular Poppy Playtime horror-game character to life. The short-form video showcases the impressive finished result of their fabrication work. It's a quick but striking look at what dedicated prop builders can achieve with recognizable pop-culture source material.
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.
