Wanting to use my Foo-roo model in a scene to show how it looked in its native environment - I created a cave for them to fly around in. Simply having a cave was not enough - I had to have more and I made more. Within the spirit of the Legends series I made a giant Refractor glowing in the middle which, of course, attracted all these Foo-roo to one place. They gave more realism to the scene and the Refractor gave a very nice light source as well.
