Warner Bros. Animation is in the midst of a boom period with over a dozen series currently in production. In addition to the much-talked-about (and unnecessarily-complained-about) Thundercats revival, the studio announced two more shows yesterday, both headed to the one-year-old Boomerang video subscription service aimed at kids, families, and animation fans.

The two shows — Yabba-Dabba Dinosaurs! and Scooby-Doo and Guess Who? — are both based on classic Hanna-Barbera properties. Warner Bros. is hoping that this type of original content will convince people to pay $5/month — or $39.99/year — for a subscription to its app, which is currently available only in the U.S. The shows will premiere on the service in 2019.

Here are the official descriptions of the new shows:

Yabba-Dabba Dinosaurs!

Yabba-Dabba-Doo! Pebbles and Bamm-Bamm are back in this quarter-hour animated comedy series, Yabba-Dabba Dinosaurs! Warner Bros. Animation takes you beyond Bedrock to The Crags, a vast land that is as dangerous and wild as the dinosaurs that inhabit it.

Pebbles Flintstone and Bamm-Bamm Rubble are two best friends, growing up in the prehistoric time when dinosaurs and giant beasts still walked the earth. But as exciting as that sounds, they live in peaceful, quiet old Bedrock, a modern domestic civilization similar to our own (but with stone cars that run on leg-power). That’s why whenever they get the chance, Pebbles, Bamm-Bamm and Dino head to the open wilderness, helping new friends, fighting new enemies, and learning about life through their endless crazy adventures. Back in Bedrock, Fred, Wilma, Barney and Betty still enjoy all the familiar quirks and trappings of life as a modern Stone Age family not knowing all the trouble (and fun!) their kids are getting themselves into.

Yabba-Dabba Dinosaurs! is produced by Warner Bros. Animation. Mark Marek (producer, MAD, Be Cool Scooby-Doo!) and Marly Halpern-Graser (executive prouducer, Right Now Kapow) serve as producer with Sam Register as executive producer.
