-Pumpkin Carving Kit (or knife)
Carve out the top of your pumpkin and scoop out all of the goop! Be sure to save some goop by putting it in a bag or bowl.
Carve out the design you want the face to be.
Now take that extra goop and string it out of your pumpkin's mouth. Now you have a vomitting pumpkin!
