Restaurant Brands International's (QSR) - Get Report  Burger King division is launching a Fruit Loops shake. Yes, for real. 

As TheStreet reported earlier this month, the shake will be available for a limited time only at participating restaurants nationwide starting Monday for a recommended price of $2.99. It's made from vanilla-flavored soft serve ice cream, Fruit Loops cereal pieces (compliments of Kellogg's (K) - Get Report ) and sweet sauce.

Burger King is no stranger to thinking outside the box when it comes to fast-food.

The company teamed up with beverage and snack giant PepsiCo (PEP) - Get Report  last year to develop what it called Mac n' Cheetos. The snack mashup was a portable combination of mac n' cheese covered with crispy Cheetos flavor. Last March, it unveiled the "Angriest Whopper," a burger with a red bun, jalapenos and hot sauce.

Jim Cramer and the AAP team hold a position in PepsiCo for their Action Alerts PLUS Charitable Trust Portfolio. Want to be alerted before Cramer buys or sells PEP? Learn more now.

And in September 2016, Burger King sold a black-bunned burger filled with Kraft Heinz's (KHC) - Get Report A1 steak sauce called the Halloween Whopper for a limited time. 

King of weird, that's for sure.
