Yeah, but that section becomes sealed off with heavy metal doors and shields, lot harder for a small worm to break through.

But once through there and you seal the doors, any crew men in that section become viable for being turned into new forms, so I can break through it with some new toys. Also, if this is happening as you say, if I manage to create a single, small hole all the way through pressure will rip the entire door out and let me go through...
