Anyway, the Reference Document doesn't mention what a Slaad looks like. Could someone decribe one to me?
They used to be like big, angry humanoid frogs. Maybe you've seen those garden ornaments with happy frogs playing musical instruments or riding unicycles? They're a lot like that, except burlier and more vicious. No unicycles. (Well, perhaps unicycles, but PCs generally wouldnt know since they seldom get to see the tender side of the Slaad race.)
