Where can you get a shovel?

This question is very obvious. At every gas station in the United States, there is a basement behind the counter. If you tell the cashier, "the goo is on the chicken," he will take you into the basement. Once you're in the basement, turn left and you will find a shovel room. DO NOT TURN RIGHT! If you do, you will run into a huge old western room with a bunch of old coots spittin' all over the place, but that's another story.
