During bath time with his kids, David noticed a discoloured watery substance coming from the rubber duck’s mouth and decided to investigate the situation.

“While bathing the children, I noticed an off-color liquid coming out of the mouth of the rubber ducky in the bath. Taking a closer look, I noticed there were dark patches on the duck’s body coming from the inside. I immediately knew what it was, and decided to make a video of me dissecting the rubber ducky and exposing the black mold from within”, David told Storyful. Credit: Viva Frei via Storyful
