Alex Hirsch, late of Disney’s Gravity Falls, is developing an animated series for Fox.

“I’m cooking up some brand-new weirdness,” Hirsch, 30, told Variety, which first reported the news. Hirsch will develop a script and presentation pilot. No details about the project have been announced yet, though it will be presumably have a more adult tone since it is being developed for a primetime slot. Fox hasn’t committed to anything beyond the pilot.

Hirsch’s Disney XD series Gravity Falls will end its run with an hour-long finale on February 15th. Hirsch made the decision to end the series himself, explaining on Tumblr a couple months ago that, “Ialways designed Gravity Falls to be a finite series about one epic summer- a series with a beginning, middle, and end.”

Hirsch acknowledged the news of the Fox project on his Twitter account yesterday afternoon:
