Miss Nancy. Why presume that penguins ONLY live --all the time--around ice/icebergs?
We have penguins close to Adelaide and who ever sees even snow here? (Today is late in the first month of Spring and it's maybe 38C!)

With say the Surface Replicator, you can have that work on a duplicate of your Terrain, and do what you want thereafter on the original terrain. It seems that you can not similarly segregate the Hair painting function.  Please tell me how if you can please!
