Good approach for sloths, even if the entire exhibit system needs some tweaks; the butterfly approach was good all in all tho and the ability to have multiple species in walkthroughs would be great.
Lar gibbon is great, can't wait to house them with siamangs. Red river hog is a fan favourite that, while not my prefered swine, will make many happy. My monitor wants were covered between vanilla and deluxe, but they are very diverse and an additional one doesn't hurt. And, of course, gotta love fossas; euplerids need love.
