In 2007, all Pixel Chix electronic toys that had been produced up to this point were now being miniaturized in the form of fun keychain lockets! Each one contained a charm inside, shaped like the character that corresponded with the original toy. A secret code was also included that could be used to unlock surprises on the Pixel Chix website, which came in a symbol format. An example code from the Babysitter Unlocket is "☻♫♫♥♦".
