I need to rig something that's remarkable similar to the worm aliens in the Stephen King adaption Dreamcatcher (http://www.imdb.com/title/tt0285531/).
What you might not be able to see from the pics is that the worm is actually much 'flatter' than it looks, and has the sides coiled around to form the tube. It's mouth actually runs the whole length of its body, and is capable of opening up along it's lengh.
Any ideas how to rig this so you have the 'worm body' control and the ability to open up parts or all of the vertical mouth?
