Bluetoes, the Christmas Elf (1988)

It's Christmas Eve at the North Pole and all of Santa's helpers are busy packing his sleigh for takeoff. All, that is, except for one sad, unnamed elf, who's too young and too clumsy to help. Then, in a dream come true, the small one ends up airborne with Santa, delivering toys to girls and boys all over the world. On this wondrous journey, the tiny elf makes a heartwarming sacrifice that helps Santa and ultimately earns him the name Bluetoes.
