As the judges look on terrified, Troy contorts his body in a way only replicated by the Exorcist.
It doesn't help that he has red eyes.
The way his joints pop out of place as he scrambles around like a crab on his back is unlike anything the judges - or audience - has seen before.
Nicole Scherzinger's reaction is basically how everyone was feeling during the performance:
The crowd literally screams as his body contorts in a way nobody should ever, ever, move.
"Okay that is not normal," exclaims host Ricki-Lee.
Troy proceeds to crab-crawl backward down the stairs towards the judges, with Lucy summing it pretty accurately: "THIS IS LIKE A NIGHTMARE."
"Guys I have never seen anything like this," squeals Nicole.
Troy then personally chooses Manu Fiedel to escort him back to the stage for what we can only imagine will be something that haunts the celebrity chef, forever.
Manu lies down on a bed, with Troy climbing backward over him while he growls in his face.
"HELP" screams Manu.
"I'm going to be looking under my bed every single night from now on. That is the scariest thing I've ever seen." Manu
"I was born very flexible" Troy explains after completing his incredible act.
"That was the freakiest thing I've seen in my life" judge Shane Jacobson claims.
Troy receives 4 'yes' votes from the judges, regardless of how they terrified they were of his performance.
