This is way better than the Upside Down!

Stranger Things actor David Harbour will be heading to Minnesota for a fun little event at Mall Of America.

Dress up as your favorite character from the Netflix hit and head to the giant mall for a fun day of events on Sunday, June 23rd.

First, head to the main rotunda around 1 p.m. There you can register to take part in the Stranger Things costume contest. (Note that you must be 18 or older to enter the contest.)

Registration starts there from 1 p.m. to 2 p.m. with the first round of the costume contest beginning at 2 p.m. From there, 15 people will win the contest and therefore win admission to the afterparty at Hard Rock Cafe, which will take place after David Harbour's appearance in the rotunda.

David Harbour will join the crowd in the main rotunda for a special Q+A following the costume contest around 3 p.m. Contest winners will then join him for the after party after his appearance.

There will also be gift cards for costume contest winners. Keep in mind that your costume can not be harmful or offensive. (More contest details here.)

The event is all in honor of Stranger Things' third season, which is set to hit Netflix on July 4th. Harbour plays fan favorite Jim Hopper.
