The four boys, alongside host Jimmy Fallon, each selected a unique dance to perform that was based on phrases from the show from a dance move generator.
After Wolfhard and Matarazzo took to the dance floor for "Toastin' Waffles" and "Flashlight With a Mind of Its Own," Schnapp had a hard time figuring out what to do for "Trying to Fix an '80s TV" as the young star was unfamiliar with television sets from the era.
McLaughlin, meanwhile, nearly stole the show with his rendition of "Breaking Through the Goo" before Fallon joined the group for "Upside Get Down" which included the late night host turning the camera upside down.
