Sesame Street parade balloons

There was a parade going on through the streets of Lancaster city, and all of the giant balloons where Sesame Street characters. There were "leaders" of the parade, who had lists of everybody's names at the parade, and their current location. Something went wrong with the Count VonCount balloon, and a little canister of Butane came flying out of his mouth. It was considered a "code red" situation and everybody had to report to their parade leaders. The Butane canister was about to crash land in a crowd of people but there was a limo with its truck wide open, which caught the rogue Butane and shut it in. The limo was dragging on the ground (apparently the Butane was really heavy?) and drove off into the distance. The area was considered safe at this point and the parade continued.
