Rayman Pirate-Community

One of my favorite creepy videos:

It is kind of silly, but this scared me when I was a kid:

I seem to recall another scene in Hey Arnold that scared me as a kid, where one of the characters developed a germ-phobia and had a vision of giant germs?

Also:

The clip that most disturbed me from that show, was the nightmare that Courage had in the last episode of the series.

And yes, claymation can be really scary:

Oh shoot, I'd forgotten the "you're not perfect" one! I don't think I ever actually saw it on TV, but I saw it in a video review about… 10 years ago

And wow, I only watched one minute of that claymation scene so far but it's quite creepy!
