Go Behind-the-Scenes of the Algae-Infected Waterpark Walkers in Fear the Walking Dead Episode 4

When Alicia and Naomi walk into the remnants of an armed standoff at the top of a water slide, things get wet and wild in a hurry.

The ensuing battle with 15 algae-covered walkers “might be the grossest scene I’ve done so far on the show,” says Alycia Debnam-Carey in a new video taking viewers behind the scenes of Episode 4.

Making of Episode 4

So what made the scene so gross?

Three words: Toilet bowl slide.

“We’re basically fighting around the edges,” of the toilet bowl water slide, “and we’ve got everybody clawing at us,” says Debnam-Carey.

Creating the algae walkers looking to devour the survivors at the bottom of the bowl was an intense process in itself.

“We use a combination of mold and different colors of slime and algae to completely cover their faces,” says Executive Producer / Makeup Effects Director Greg Nicotero.
