‘Stranger Things’ actor to help save (and dance with) penguins in Antarctica — and it’s all thanks to Twitter

"A man needs his 'guins," "Stranger Things" actor David Harbour wrote on Twitter Monday, begging users to help him make his dancing-with-penguins dreams come true.

Harbour, who plays Hopper in the hit Netflix series, first sought the attention of global conservation organization Greenpeace Saturday, wondering what it would take to "send me someplace to tell emperor penguins I think they have terrific parenting ideologies? Perhaps hone the Hopper dance with the males..."

Greenpeace responded to Harbour and said that if he could garner more than 200,000 retweets, they might be able to make his dreams come true. “#StrangerThings have happened...” the organization wrote.

Greenpeace is currently campaigning to create an Antarctic Ocean Sanctuary — "a safe haven for penguins, whales and seals" that would be off-limits to fishing vessels.

“No business is worth sacrificing a whole ecosystem for and world leaders shouldn’t allow an ocean wilderness to be exploited by a handful of companies,” the Greenpeace campaign states. “Healthy oceans sustain precious wildlife, help limit climate change and provide food security for billions of people.”

Lucky for Harbour, in less than five hours, more than 300,000 fans jumped in to help with the click of a button. It was a done deal.

This isn’t the first time Harbour’s Twitter challenges have driven big results.

Just days ago, Harbour agreed to officiate an Illinois wedding if he received at least 125,000 retweets (and he did).
