Besides the species of sloth, the animal choices are kind of hard to be mad at. It is more the composition of it, I guess. It feels like two bases for good packs have been boiled down to one mediocre version of it.
Had the sloth, gibbon, and fossa been together with a New World Monkey and something like a New World Porcupine or a Tree Kangaroo. Then we would have a solid arboreal pack, with potential for useful scenery too.
Then let the red river hog and monitor be in a Tropical Animal Pack together with some birds, a monkey, perhaps a tortoise or coati. Plenty of options here.
So besides the obvious lack of birds and monkeys in this tropical pack, it is not so much the choices here that annoy me, as it is the wasted potential.
That is the feeling I'm sitting with right now.
I'm really excited to see the brachiation being better, that alone makes me happy to get the gibbon, even though a monkey is much more needed.
The fossa and red river hog are somewhat logical choices for PZ, so I will not say anything bad about these choices, though I would be fine without them.
The monitor stops this from being another complete mammal gathering and adds another non-crocodilian habitat reptile, so that is interesting.
The walk-through exhibit is screaming for a bird, so I am not satisfied with the sloth, to be honest...
