2017 Days Of The Dead - Atlanta, GeorgiaThe "Stranger Things" kids smack talk like they do most other things: adorably.

Four of the show's stars -- "Lip Sync Battle," so the hosts of the preshow helped them get their game faces on. The young actors were each given the chance to "rattle some cages" and intimidate their co-stars, but as good as they are at acting, a couple of them seemed to have missed the finer points of talking trash.

"I think I might win ... But I think you guys might win, too," Schnapp said.

McLaughlin was even worse -- he offered encouragement instead of fighting words: "Do good out there."

Luckily, Wolfhard saved it all, busting out the big guns by bringing up how Matarazzo's "Les Misérables" character died every night. "That's going to happen again tonight," he said.

Spike released two promos for the episodes, including one of McLaughlin performing LL Cool J's "I'm Bad."

The other video teased Wolfhard's rendition of "Buddy Holly" by Weezer.

"Lip Sync Battle" airs Thursdays at 10 p.m. ET/PT on Spike.
