Panellist Jackie O admitted she wouldn't want to give birth to the Baby, but fans are already creeped out.
"Alright, who had the fever dream idea that is demon baby?" one person penned on Twitter.
But someone has already guessed as to who the giant infant really is.
"Early call - Baby = Ann Edmonds," one fan speculated on Twitter.
Whoever thought of this costume deserves a raise.
We all know this is the Aussie drunken food of choice, but as for who is singing disguised as one, we're less sure.
Names including Neighbours star Alan Fletcher, Kate Langbroek and even Rita Ora have been suggested.
In the latest trailer, Mullet literally lost their head but still managed to conceal their identity.
However fans are convinced it's a certain ex AFL legend.
"It's none other than boundary riding legend himself (with a fine mullet to boot) Robert 'Dipper' DiPierdomenico," one penned on Twitter.
"Mullet is Dipper surely," mused another.

This costume's one of the more abstract ones but Atlantis could be an Olympian.
"Atlantis, somehow beeped with a metal detector. Prediction: Susie O'Neill. Susie's first Olympic gold medal in the pool, was won in Atlanta in 1996. This is why Atlantis beeped when the screening wand went over her," one eagle-eyed fan wrote on Twitter.
Though everyone is stumped when it comes to Vampire, this contestant is already creeping people out on social media.
"Vampire looks like something that would have gotten you eliminated on Face Off," mused one.
"I will have nightmares about that vampire mask," wrote another.
This cutie is already a fan favourite.
“Piñata already has my heart,” one fan confessed on Instagram.
Some are convinced that it's radio personality Michael 'Wippa' Wipfli, who has been very tight-lipped about it.
"I don't know why there was a link being made to me being a Piñata... but I can't talk about it," he shared on his and Fitzy's breakfast Nova show.
One food themed costume was not enough, it seems.
The first season of The Masked Singer New Zealand also had a pavlova who was revealed to be Shortland Street star Stephanie Tauevihi, but we're stumped for who this could be.
Duster - George Calombaris
When Duster revealed they're "always busy" but "whether you like me is a matter of personal taste," we had so many thoughts.
Guesses ranged from Shane Warne to Michael Clarke to Gordon Ramsay, so imagine our shock when they were revealed to be former MasterChef judge George Calombaris!
"I can't believe I've just done this, this is so insane! 11 years of MasterChef, that's pretty easy compared to this," he declared, adding he did the show for his two kids.
Volcano - Vinnie Jones
This hot-tempered celeb declared, "I'm a hottie and you don't want to be around when this volcano starts smoking!"
So when they were revealed to be British actor and former professional footballer Vinnie Jones, we were genuinely stunned!
"I never thought I'd meet you and you'd be wearing this outfit," panellist Dannii Minogue confessed.
