Trick of Fixer

From BoardGameGeek:

At this zoo, animals play a game every day to decide who is the boss. The animal that wins the game becomes the boss, but it cannot become the boss without the help of not only its own strength but also the help of its fixers (friends) who work behind the scenes. Who will win the title of Boss? Let's get started! Trick of Fixer is a trick-taking game that you can play over and over again based on your favorite card game Napoleon.
