A deck of English Uno cards from 1994. This particular deck uses the older card design, where letters appear on the action cards instead of symbols. The deck consists of 108 cards, of which there are twenty-five of each color (red, green, blue, and yellow), each color having two of each rank except zero.
While bees and wasps inject venom when they sting, mosquitoes simply bite to feed on your blood. The bumps and itchiness that follow come from an anticoagulant that the mosquito injects to prevent your blood from clotting, which triggers a mild allergic reaction that includes the typical round, red bumps.
