I can't remember this one old show...?

I can barely remember it. It seems like it was made my Jhonen Vasquez
(creator of Invader Zim.)
Its about two twin boys, one is an evil genius >I think he had a
grayish tinted skin colorVERY small. He, I think, used stilts at one
time to be tall. <

That's about all I remember. It might have been on Nickelodeon.
