What can I use as a substitute for Nori Wrapper on a Chocolate Dessert Sushi? I'd like to make a chocolate dessert sushi but I'm stuck trying to come up with a substitute for nori or rice paper.  I know some people like to use plastic chocolate like in this question.

However I'd like to do something different to compliment the chocolate on the inside of the roll.  Nori and ricepaper don't seem like they would work well for a dessert. 

So if anyone has an idea, I'd love to hear it. 

As a bonus, has anyone tried using something other than coco rice krispies for crunchy?  They tend to get soggy and lose their crunch if you wait too long to eat them.
Green fruit leather makes a good substitute for nori in dessert "sushi" rolls, if you're going for something that reminds people of sushi without being creepily realistic. (I recently made a variation of these dessert sliders for Independence Day and they were a little too realistic for people).
