Cartoon Network US has ordered up additional episodes of its three new boys-skewing animated series – Adventure Time, Regular Show and MAD – that anchor its Monday night comedy lineup.

The first two seasons of Adventure Time ranked number-one in its timeslots among kids and boys ages two to 11, six to 11, and nine to 14. The series, which follows the unlikely heroes Finn and Jake as the traverse the mystical Land of Ooo and encounter its colorful inhabitants, is currently in its second season and is now greenlit for a third.

CN’s new original animated series Regular Show debuted in September 2010 and has been greenlit for a second season. The series features best friends Mordecai, a six-foot-tall blue jay and Rigby, a hyperactive raccoon, whose attempts to escape their everyday boredom take them to fantastical extremes.

Warner Bros.’s original series, MAD, which is rooted in the iconic magazine, will also return for a second season after increasing key kids and boys audience ratings and delivery, ranging between 31% and 71% across the board.
