Thoren (The Secret World of Santa Claus)

Guilfi is the tallest elf at the workshop and is great with mechanics. He wears a red hat and constantly has his sleeves rolled up. He has not graduated to the level of Master elf like Thoren or Jordi; hence why he is usually left at the workshop and has no powers (until the last episode where he develops). But santa Claus take Guilfi with him sometime when Jordi can't go, or go in mission with Jordi and Thoren. He's maybe the youngest elf, but also learn Russian language after go to Kalicagrad with Jordi Balbo Thoren and Santa Claus
