Voadam
Legend
I also think Slaads are a poor design. Aside from their chaotic evil behaviour, I just think they don't seem "chaotic" physically - they are too predictable. They ALL look like toads - why? What's chaotic about a toad?
Frogs are a mythological symbol of change and transformation. They go from eggs to limbless waterbound tadpoles with tails to adults with legs and no tails who are comfortable on land.
For example see the Ogdoad, eight primordial gods of really ancient Egypt who arose out of chaos, half of whom are frog headed.
