As explained by @FNBRLeaks on Twitter, decoding the number 067 000111 as ASCII and Binary respectively reveals ‘C7’, the coordinates of Greasy Grove on the map.

While it could hint at changes to come in Season 5, this may simply be a reference to the location of the burger in-game without any significant alternative meaning.

Update #1: People visiting the area have been given a phone number by an ‘Agent’ to call for additional clues on the meaning: (712) 380-4091.

With a lot of speculation that Epic might introduce a desert map with Season 5, this appearance could be a marketing stunt to advertise it’s release. Along with the mascot, a police car resembling those found in the game was also be found at the scene:

We’ll be sure to update this post if any other objects appear, hopefully we’ll see the Tomato Town head again soon!
