[bi-] Bigfoot is in the [3] basement of the [-an] pawn shop where he is organizing some priceless 貝 shellfish that they have stored down there. Suddenly 之 Zorro comes down a 丿 slide that is near the 貝 shellfish, knocking right into them, and afterwards cutting a Z onto some of them. Bigfoot is angry because this has 貶 diminished the value of each of the 貝 shellfish, which were in mint condition. Some of them were completely destroyed, so their number has also been 貶 diminished. Bigfoot goes into a rage and starts to chase 之 Zorro, hoping 貶 to diminish the chance of him doing any more harm.
