Good catch, I'll add it to the list. I watched the Show Stoppers on TV with my little bronies a few days ago, and at one point the CMC are diving in what seems to be a lake or river, and get chased by a big, blue squid. I'm inclined to make lake/river squid a thing. Adds a little danger, and for the seriously crazy, setting up a system to drain a whole river to harvest them will be quite rewarding.
I'm just about finished with transferring the changes to the raws(gizzards, tongues, new benign tags and that). I've implemented and tested wing feathers on pegasi, and since it works, I'll roll it out across the others. I'll be interested to see how honey badger pegasi react to that, I can see that being a nightmare to debug, or maybe I'm just paranoid about creature variations. I'll give the various animal ponies pretty low frequencies, since they're being complained about enough in vanilla, with the zebra/buffalo/lion varieties it's going to be something of a clusterbuck. I'll probably do some pruning, maybe limit pony and buffalo to temperate creatures and zebra and lions to tropical, with a little overlap.
