What should a Green Iguana have in it's tank or cage? - blueprints for cages

I am a school report, where you need to do a project for the reservoir of iguanas and wondered if something special must be in a container. I know I should not hot stones, branches, etc. I wonder if there are any toys or anything in particular in the cage or tank.
