Rain for the Rainforest

So where do you get the rain for a Rainforest ... well in S.L. .. easy ... you just go to a shop and buy one (or two) clouds.
Then all you do is put it in place ... then when I (as the owner) click on the cloud I get a blue drop down menu appears in my S.L. viewer ... which gives me the options of what the cloud can do .... nothing, light rain, heavy rain .... or even snow ... UUMmmm .. don't think it snows much in Rain Forests .. right?
