Millie Bobby Brown is a champion for justice both on screen and off.

After eight classmates failed to show up to a young fan's Stranger Things themed birthday party, the Eleven actress vowed to attend his next bash, going so far as to RSVP on behalf of the entire cast of the hit Netflix series.

On Sunday (March 18), a little boy named Aaron's older sister shared what had happened on Twitter. "My brother invited 8 of his classmates for his stranger things themed bday party & none of their punk selves showed up," the little boy's sister tweeted, sharing photos from the party—including pictures of the first season's signature Christmas tree light decorations and a both terrifying and delicious sounding bowl of "Demogorgon Blood" punch.

After noticing the tweet, Brown replied, "What!!!! Oh Well You can let them all know that everyone on behalf of Stranger Things would’ve come! I think you’re awesome and next year I would like an invite… Please?"

But the actress wasn't the only Stranger Things cast member to share their support: Gaten Matarazzo, who plays Dustin on the show, added, "Count me in too! I'll bring the chocolate pudding."

We'll bet his classmates really regret ditching now.
