Popplio's final evolution is a quite slender sea lion who's arms and body colors, plus some seaweed and other items like it, give it the appearance of wearing a kimono that has the design of the tides themselves upon it.

One final riddle for a final bit of information. This time, for a pokemon that has NOT been revealed yet. For the final time, RIDDLE ME THIS:
I am found usually within the woods.
Those who find me consider me to have a sharp wit.
And those who harm consider me a friend.
What am I?
