A cartoon of the Colonel Sanders’s face will pop up as you swipe and he will grow bigger before your eyes until the menu suddenly appears.
The menu description reads: 'Discover unreleased treats that have never seen the light of day - until now. I update the menu regularly so keep checking back.’
The new menu was discovered by one savvy KFC fan who posted it on The Discount Mum's Facebook group.
'A friend pointed out a little secret. There is a secret menu with some super secret (and hilarious!) goodies! Well not so secret anymore,' a mother said.
'Scroll with one finger and hold it in place and with another, keep scrolling until you eventually see his head pop up.
'Just keep scrolling for dear life. He will get bigger and bigger. It may take a few attempts but keep trying!'
KFC later confirmed to the mum that the secret menu is available at all stores across Australia.
So what’s on the Secret KFC Menu? At the moment there are three items available, including a low-carb burger known as The Slida Burger - consisting of a Zinger fillet, smoky bacon, fresh lettuce, cheese and sauce all packed between two flatbread buns.
The Beese Churger, meanwhile, is a regular burger with a Zinger fillet, cheese and mayo - but the buns are flipped upside down. Says KFC: 'Honestly, we're not sure how, but it really works, trust us.’
And last but not least, The Zinger Hipster is described as a ‘next level’ Twister with a Zinger fillet, lettuce, cheese and sauce - wrapped in a tortilla and stuffed with KFC chips. Lordy,
All items are $6.95 - but you have to get in fast before the Secret Menu changes. Again!
