"Big River" giant catfish

[richak]

I need ideas. It needs to be pretty large, 5 or 6', and it is "gutted" so props fall out of it.

This is my first time working on this show. How have you seen it done/made? Any ideas would be great! Thanks!

I saw one that appeared to be cast in flexible foam. If you're not familiar, check out smooth-on.
