Changes to McDonald's burgers

Changes to the burgers include softer sandwich buns, which are toasted golden brown, "perfectly melted cheese," and a "juicier, caramelized flavor from adding white onions to the patties while they’re still on the grill," the company previously told USA TODAY. Big Macs will also be served with more sauce.

“It's no surprise these changes caught the attention of our biggest burger fan – the Hamburglar," Tariq Hassan, chief marketing and customer experience officer at McDonald’s, said in a release. "We’re excited for fans to join in on the fun as they look for him on his burger-stealing spree. You never know where he’ll pop up next.”  

How to spot the Burgercuda at McDonald's

The Burgercuda car features the Hamburglar's signature black-and-white stripes across its interior and exterior, along with red detailing and the mascot's logo on the headrests.

The getaway car also features bun-like hubcaps, a spare tire designed as a giant cheeseburger and, because details matter, a hidden burger warmer in the center console. The Hamburglar's signature catchphrase, "robble robble," appears on the hood scoop and on the license-plate as "RBL RBL."
