Mr Elf is a minor character in the series. He is Ben's father and Mrs Elf's husband, and resides with them in the Great Elf Tree.
Mr Elf is diligent, organised and sort of strict. He can be described as a 'workaholic', as he is always working compulsively and finds it genuinely difficult to relax.
He likes to keep a schedule of things and makes sure everything he does follows said schedule.
