17 '80s-Inspired Easter Eggs in "Stranger Things" Season 4

While the Hawkins crew is on the run, hilarious new addition Eddie throws on a white mask — aka the iconic Michael Myers mask from the Halloween slasher-film series. It's a twofer Easter egg, too! Not only does the mask reference the Halloween series, but it's also a throwback to the Halloween episode of the second season, where Max wears the same mask and startles the boys.
