Starting February 1, 2003, the animated series Rugrats and Chalkzone will join CBS Saturday morning line-up known as Nick on CBS. The long-running Nickelodeon favorite Rugrats will air at 7:00 a.m. The stop motion animation-heavy Chalkzone will be seen at 8:00 a.m.
Other changes include moves for both Dora The Explorer and Blues Clues. The pre-school series will go from early morning slots to air late morning. The animated series As Told By Ginger will no longer be part of the block.
