Tiny has been Magee's assistant for 89 years. He won the position after a rigorous interview process over more qualified applicants with his encyclopedic knowledge of Christmas Eve protocol and his ability to carry several scalding hot mugs of eggnog lattes through six feet high snow drifts.
Prior to his current vocational path, Tiny was a well-regarded athlete among the elves at the North Pole. He was a champion reindeer jockey and an all-star center on the Holiday Hoopsters basketball team before an unfortunate shoulder injury suffered during tree trimming festivities prematurely ended his athletic career.
Tiny's whole body is never really seen, expect for his hat.
