Hint: More lives:
Go to Burgerworld. Go all the way behind the store on both sides, practically against the wall. You should find hotdogs for more life.

Go to the far right side at the dumpster in Burgerworld, where the green hamburger is located. Every few seconds, Beavis will say, "We're sick". Go to the hospital and enter the room marked "Keep Out". All life should be restored.
