Avery is a savant at training all sorts of animals, no matter how wild or stubborn. If they come, she can train them. Besides training animals for the daily show at the zoo, she has been assigned with training them to obey commands from the boss. When the time is right, the boss will use these highly trained animals to be spies and carry out classified missions.
Each mastery level adds another card to the cardpool for defeating Avery. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
