foolish / stupid / expressionless / blank / to stay
The fool wants to make fun of Don Quixote in front of the airplane. To fool him, he set up a Christmas tree to look like a huge animal by putting a mandarin on top which looks like the head of the animal. Don Quixote thinks he met his arch enemy and starts to charge the construction, much to the fool's delight.
In front of the airplane someone devoted huge black sneakers to the local buddhist shrine. Don Quixote fits into them with his whole body and the sneakers are so cozy that he thinks he could stay like this forever.
