Hanna-Barbera has never been afraid to play around with their characters, as seen with Adult Swim series like Sealab 2021 and Harvey Birdman: Attorney at Law. Now, all the animation studio's classic characters are coming back to life in the latest trailer for Jellystone!, the upcoming HBO Max animated series.

Jellystone! follows a whole list of Hanna-Barbera characters as they "live, work, play and (as is often the case) destroy the town in some silly way together." Characters like Yogi Bear and Boo Boo, Huckleberry Hound, Jabberjaw, Magilla Gorilla, and Peter Potamus populate the town and interact regardless of what show they originated on.

If you recognize the visual style, it's because the show comes courtesy C. H. Greenblatt, creator of The Grim Adventures of Billy and Mandy, Chowder, and Harvey Beaks.
