Cartoon Network picked Thursday to announce a lineup of new, green-lit shows and the return of a couple successful 2008 outings.

The two new original comedy animated series include Regular Show and the intriguingly entitled Horrorbots. The former was developed by the network's sort of "animator in training" developmental system, Cartoonstitute.

Regular Show is created by J. G. Quintel and was developed as a short for the development program. In each episode, "two bored groundskeepers, Mordecai (a six-foot-tall blue jay) and Rigby (a hyperactive raccoon) are best friends who spend their days trying to entertain themselves by any means necessary, much to the displeasure of Benson (their boss, who is a gumball machine) and to the delight of Pops (an older, lollipop-headed gentleman)."

Cartoon Network has five new shows kicking off this year. They are:

• Re-Animated: a new series based on the original Cartoon Network movie about a young boy who has his brain replaced with that of a famous animator and begins to see the animator's creations appear in real life.
• Chowder: the story of an apprentice to a famous chef named Mung Dahl. Chowder wants to be a master chef, but he eats everything he sees. Chowder was created by C. H. Greenblatt, who previously worked on SpongeBob SquarePants and The Grim Adventures of Billy and Mandy.
• Currently untitled Santo series: Originally developed by Cartoon Network for Mexican audiences and based on the legendary Santo the Silver Masked Man, this new series will see the famed wrestler win bouts inside the ring while fighting vampires, monsters and robots outside the ring.
• The Secret Saturdays: Doc, Drew and Zak Saturday are scientists who work together to save the world from strange and inexplicable events. As part of a network of scientists, the trio battle the evil V.V. Argost and a mutant half-giant / half-spider.
• The Marvelous Misadventures of Flapjack: Out of all these new series, this one looks the most interesting to me. Creator Thurop Van Orman's (Powerpuff Girls, Camp Lazlo) series focuses on a young sailor named Flapjack who lives inside a whale named Bubbles and listens to tales of the sea from a pirate named Captain K'nuckles. There's a great interview with Van Orman on the Frederator blog, along with some images from the upcoming series. I'm absolutely enamored by the design of this cartoon.
