What's inside a tropical fish capacitor?

I noticed that the clyde style wah on the fuzz central site has these.  Why use them?  Does it really make any difference?  Is there a modern equivalent?

[Paul Perry (Frostwave)]

I believe these are polyester in which case, modern greencaps would do (note some greencaps are brown??)

A guppy, and some blue smoke.

I just ate one and it tasted a whole lot like chicken.

Seriously though, if they are just polyester why bother getting them.  Because they look purdy?

I think those are metallized polyester film.
