Netflix is flexing more muscle in kids’ programming, announcing an original series from Hasbro Studios based on Stretch Armstrong, the blond gel-filled toy bodybuilder popular in the 1970s.

The streaming leader also announced the pickup of live-action tween drama “The Greenhouse” and animated series “Lalaloopsy.”

The 26-episode Stretch Armstrong series, Hasbro Studios’ first original programming for Netflix, is slated to debut in 2017. The animated animated action/comedy series is about an over-scheduled teenager named Jake Armstrong and his two best friends. Then the trio are accidentally exposed to an experimental chemical, they become Stretch Armstrong and the Flex Fighters — a team of stretchable superheroes.

Hasbro has tried to turn Stretch Armstrong into a film property before. Relativity Media cut a deal in 2013 for a live-action movie based on the action figure but passed on the project; that came after Universal Pictures backed out of plans for an adaptation produced by Brian Grazer.

“With roughly half of our 75 million members regularly watching kids content, we’re happy to expand our original slate with these three great series,” Andy Yeatman, Netflix’s director of global kids’ content, said in a statement. “We know kids love Netflix and that’s in part because they never really outgrow us.”

“The Greenhouse,” also set for 2017, comes from Nutz Productions, a subsidiary company of Ananey Communications. The series is set in an elite boarding school in Southern California, where students are divided into two rival houses that must join forces to conquer challenges when an evil plot is uncovered. Paula Yoo (“West Wing,” “Defiance,” “Eureka”) is adapting with showrunner Giora Chamizer, who wrote and created the original series.

“Lalaoopsy,” based on the line of dolls from MGA Entertainment, will feature original music and follows the misadventures of six friends and their pets through a whimsical world. The 13-episode series is scheduled to premiere in the fall of 2016.
