Hayzee lived in Jazzafrazz Town, where he wrote a musical called "The Mystery of The Fiery Hat of Social Awareness" for the annual Jazzafrazz Town Drama Slam. As it turned out, the compass piece that Luigi needed was a part of the prize for winning the Drama Slam. So, Luigi became an actor in Hayzee's play. While Hayzee played the part of The Red Miracle, Luigi, much to his dismay, played the part of grass. In the end, their musical was most popular by far, they won the Drama Slam, and Hayzee joined Luigi on his quest.
In this upcoming game, Hayzee appears as a playable character with an assortment of healing and status attacks, making him one of the most useful people in Luigi's party. He usually protects Luigi in times of crisis, as Jerry and sometimes Screamy do.
Allied with grass
When Luigi came to Jazzafrazz Town in Paper Luigi: The Thousand-Year Compass, Luigi had to win the Drama Slam in order to get a piece of the Marvelous Compass. Luigi was part of Hayzee's play in the competition, and with the best singing, they won the Slam! Hayzee seems to be the only partner who does not see something wrong with/absolutely hate Luigi.
