I know it's probably not relevant to this pack but I feel like we don't talk about lorises enough. Imo it's more important to have than the sifaka. We already have three lemurs. Any loris is a zoo staple for me and no nocturnal house feels complete without them. They're one of my favourites to find because you usually have to peer for a long while to spot them, and when you do its so rewarding. Their movements are so funny. I have a childhood friend who I enjoyed watching them with at Shepreth once and ever since we sometimes do this freaky loris crawl movement handshake thing and it cracks us up every time. 20 year old jokes are the best jokes amiright?
Plus zoos are essential for their conservation. London Zoo labels them as an EDGE species: Evolutionarily Distinct and Globally Endangered. I was so surprised they didn't come with the Twilight Pack and I've since been hoping for a nocturnal follow up, but that seems unlikely now. So I hope they do get a slot in the fabled Zookeeper Collection or whatever pack, if and when it comes.
