Trying to find old cartoon network social game

Basically it was kind of like CN's answer to Nicktropolis if I remember. You could go to different worlds and if I remember correctly it had minigames. I remember you could get like in game items based on CN shows, for instance there was a commercial saying if you put in a certain code you could get Chowder's hat.

I don't remember the name of this but it has since been ended and I was wondering if there was any way to access it.
