(1)Korea Customs Service sniffer dog
(2)A puppy excited at the thought of going to work
(3)When you go to work, you can run around and smell this and that
(4)I found a drug, so I’m making a fuss about a towel-biting game as a reward
(5)If nothing comes out for a few days, the puppies think that they didn’t do well and are depressed
(6)It’s a fabrication that allows you to find it after putting it in a similar scent bag
