Pixcodelics

It takes place in a fictional city called Lowpolys within the "world" of the internet, and tells the story of four children named Pix, Nerd, Hack and Mary Chat, (all created by emoticons) who possess special artifacts that give them incredible powers so that, with the help of the mysterious oracle Dotcom, they can fulfill the important duty of saving the internet from the dangerous plans of the evil and brilliant scientist Dr. Ping and his clumsy feline assistant Katslock, who returned from the future with the objective of preventing the "World Peace" that the internet later brought about.
