Really bad *** Green Dragon

[fnork de sporg]

So I'm going to have my high level party fight a powerful green dragon champion of tiamat. Mostly just because I bought this really killer green dragon toy and I can't wait to use it in my game. It's really really big so I want him the encounter to be worth the drama of it's mini.

Any thoughts?
