Remember the cartoons they used to show?

I remember when I first watched this show they had cartoons in it. I can only remember 2; one about anthromorphic shoes and one about a claymation couple who... do things. I would recognize it if I ever saw it again. I remember when it came back to Nickelodeon when I was older, I was disappointed that I never saw any episodes with cartoons in them. Does anyone know where I can watch episodes of Eureka's Castle with those cartoons in them online? I would love to see some again.
