The skunk's front door changes throughout. The doorknob changes its location. The lock and hinges disappear and reappear. Sometimes the door opens inward, sometimes outward. The hinges (when shown) are on the inside of the door, but it opens outward (impossible).
The skunk is shown 'spraying' out the tip end of his tail. The skunk's scent glands are actually anal glands, and, therefore, are located at the base of the tail.
