What this video covers

This first part of a mold-making series from Stiltbeast Studios walks viewers through creating a one-piece mold using 100% silicone caulk. The process involves thinning the caulk with naphtha to achieve a workable consistency suitable for capturing fine detail. It is aimed at SPFX artists and haunt builders who want an affordable alternative to commercial silicone systems. Proper ventilation is emphasized throughout due to the solvents involved.

Key takeaways

  • 100% silicone caulk can be used as a budget-friendly mold-making material
  • Naphtha is used to thin the silicone caulk to a more workable consistency
  • A well-ventilated workspace is essential when handling naphtha
  • This is part one of a multi-part mold-making series

Who this is for

SPFX artists, haunt prop builders, and mask makers looking for a cost-effective silicone mold-making technique using readily available materials.

Materials mentioned

  • 100% silicone caulk
  • naphtha

⚠ Safety notes

Work in a well-ventilated area when using naphtha, which is a flammable solvent. Avoid open flames and wear appropriate respiratory protection.

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.
