It starts on July 8th 2013, but as with the comics, Mum and Dad have been redesigned. The cast has changed as well, with Dennis having a new voice actor. Basically, it's not a second season after all, but rather, a reboot.
Cowboy Bebop at His Computer: It's often assumed by the media that Dennis is no longer whacked with a slipper at the end of each strip because it wasn't politically correct. In truth, the practice of slippering had already become old hat by the time it was axed in the comic, and getting rid of it allowed for less predictable endings.
