I remember this toy! Wow, Tyco must be where old molds never die.

I don't know of any pieces which would fit the shape, but then of course, I'm
really not as up on my piece knowledge anymore. There doesn't seem to be a
"worm segment" piece other than the actual regular worm piece Chris loves so
much. There are those neat Castle stairpieces which are a "sweep of arc" but I
don't think you could make a giant worm out of them.
How about tirehub cylinders wrapped in flextube?
