'Stranger Things' season 2 Super Bowl ad teases the return of Eleven, Halloween premiere date

A trailer for season two of Stranger Things aired during the Super Bowl on Sunday, teasing the return of Eleven and the upside down world.

The promo video kicks off with an old Eggo waffles commercial, a nod to fan-favorite character Eleven. The commercial then cuts to Eleven opening her eyes as Mike yells for his friend. Stranger Things fans will remember the young girl with powers went missing after helping rescue Will from the upside down at the end of season one.

Stranger Things season two will premiere on Netflix on Halloween (Tuesday, Oct. 31).
