The point is, there are 30> individual animal powers, categorizing them would be much better, because then you have a few animal smilies with nice effects and not just: figure - cry, laugh, sad etc.. Its such a waste that could be used to make better powers.
But since that can't/better should not be changed afterwards, its rather a tip for them to get away from this attitude.
So instead of snake with 10 similar boring smilies you become:
Jungle -> Snake, jaguar, gorilla, rhino, sloth, tiger, Crocodile, bear, tapir, flying fox, etc.
