String Finger Theatre, Episode Four: Revenge of the 3rd Dimension

In a world with only two dimensions populdated by stick figures, a dedicated few remember when evil mad scientists attempted to use the third dimension to take over the world. Now, Reformed Evil Mad Scientist Cat, Reporter/Private Investigator/Police Officer Mike, and Washed-up Superhero Zed remain ever vigilant for incursions from the higher dimensions. It looks like that time has arrived, as third dimensional critters make it clear they seek revenge, and it looks like Mike, Cat and Zed have very little time to foil Evil Mad Scientist Carmack's diabolical new plan and save the world. Reproducing the fourth storyline from the web comic in dead-tree format, this is STRING FINGER THEATRE.
