J.G. Quintel’s new “Regular Show” and Craig McCracken’s “Foster’s Home for Imaginary Friends” spin-off both feature in a new production slate from Warner Bros. Animation, Cartoon Network Studios and Hanna-Barbera Studios Europe.

Unveiled Wednesday at Annecy, they join a new “Adventure Time” series, “Side Quests,” as greenlights at the Warner-owned companies.

The news slate also boasts two more “Adventure Time” shows in development, plus an unannounced Scooby-Doo project.
