What this video covers

This short Hauntcast clip demonstrates a simple technique for crafting creepy larvae sack props using Great Stuff expanding foam sprayed over punchy balloons. The result is an organic, grotesque prop suited to swamp, mire, or village haunt environments. Despite the minimal runtime, the core concept is immediately replicable with widely available, low-cost materials.

Key takeaways

  • Punchy balloons serve as the underlying form for each larvae sack
  • Great Stuff expanding foam is applied over the balloons to create a lumpy, organic texture
  • The finished props work well in creature-lair, swamp, or infestation-themed scenes
  • Very low cost and beginner-friendly build

Who this is for

Home haunters and haunt builders looking for a quick, budget-friendly organic prop to add a creepy infestation feel to their scenes.

Materials mentioned

  • Great Stuff expanding foam
  • punchy balloons

⚠ Safety notes

Great Stuff foam is an irritant and adheres aggressively to skin; wear gloves and work in a ventilated area.

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.
