A taco is approximately 6” long, 4” tall and 2” wide. That gives it a volume of ~48 cubic inches. With that many tacos, that gives about 200k cubic feet of taco. That’s a cube about 60 feet on a side. That’s a basketball court covered 43 feet deep. Assuming he’s in a room rather than a huge area, he’ll very quickly be buried alive in tacos. I’m sure he’ll die happy!
