Cartoon Net goes online

With hopes of using the Internet as a way to test pilots, the Cartoon Network will debut two original cartoon series online Monday, with plans to debut five more by next year. The two shows are "Pink Donkey and the Fly," about a crazed fly in love with a pink donkey, and "B. Happy," about an unusually happy bluebird who wants to rid the world of misery. Both shows will appear on the cable network_s year-old Web site at www.cartoonnetwork.com. As each show unfolds, users will be invited to branch off the narrative at certain intervals.
