Brynley's Fiji mermaid
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Brynley brings in a replica of a Fiji mermaid (a common sideshow exhibit typically featuring the head and torso of a monkey sewn to the tail of a fish) which she had made out of clay. Guy describes it as looking like “Satan’s buttplug”. She earns third place.
