Big Macs went extinct? I have to say I haven’t seen one in the wild for some time now, and that one appeared to have devolved to a smaller (and less tasty) state compared to its ancestors. I guess natural competition had its way, if there’s anything natural about the fastfoodosphere.
You are looking in the worng places, The marine Big Mac has a solitary fin on top that slices the surface in shallow waters frequented by humans and seals.
You can wade right in and pick one up for free!
You will likely never try more than once.
