Millie Bobby Brown gave Stranger Things fans a Halloween treat when she recapped Season 1 of the Netflix series via a cheeky rap session on The Tonight Show.

At the behest of host Jimmy Fallon, Brown made it easy for those who wanted to catch up before taking in the events of Hawkins, Indiana, in the show’s second season. “I have to do a recap of Season 1 so people can watch Season 2 and know what they’re talking about,” she told Fallon before the show’s band, the Roots, dropped a beat.
