Jack Frost is tired of the negativity that goes with his job. Everyone complains about the cold and the snow. No one appreciates the beauty. They only care how it inconveniences them. Bunch of ingrates!
He wants a new job. He's in your office at Career Counseling For Magical Beings. Get to know him. Help him find a job he'd be perfect for.
In the process, perhaps after he's tried some of these new jobs, talk about what other magical beings have said they'll do or are doing with his Jack Frost job.
