Yes, I noticed that too; rabbits appeared out of nowhere for me as well :(. Well, it seems "Buka" really went all out here.

Regarding the animations: Vanidzamé play on their clubs, as mentioned before, and Kenshi try to chop off their tails :). Kappas are funny with their tongues, and if you wait, they stand on their hind legs and start stomping – giants, in a way :). Coral priestesses also dance, and we already talked about the nymphs (snow nymphs shiver from the cold, and fish fall out of the river spirits, which they stuff back in :)). Kirins, on the other hand, strike a "rabbit pose" – they jump on their hind legs.
