Given that the Oceania map is useless to me, I've started a new zoo in Scotland again (Kinross Zoo, my usual go-to name).
I've used some workshop items. The interior of the Zoo-Venir shop is by
@Shiftzie (thanks!), and the Zoo Tyoon 1 Elephant Fountain is by a Steam user by the name of GiornoPizza. This is probably the most detailed zoo entrance area I've ever built, because honestly I hate detailing. This has taken me all day by virtue of the fact that I have to keep leaving and coming back to avoid half-assing it.
The plant pallet will remain the same throughout the zoo. I'm not great at landscaping so I prefer these haphazard "wild gardens" over deliberately-placed and well-ordered flowers and such. I've used the Lady Fern, Flowered Siberian Peashrub, Common Saltwort, and Dog Rose Bush, which makes quite a pleasing mix I think.
Only staff facility I'm missing is a vet clinic (out of the ones Sandbox actually needs, that is). I did attempt to make my own custom doors/windows for parts of it but, again, detailing sucks. I've subscribed to some Animal Doors on the workshop (by Mesanii) that I'll probably use for backstage buildings when I get around to adding habitats, and some neat little decorative nest boxes (by Zimfira) too.
Anyway, once I've put in a vet clinic...somewhere, I need to decide on my first habitat. I'm feeling low-budget for this zoo with a few high-budget "big ticket" inclusions. I'd like to use the bubble dome as well, so maybe meerkats (my usual starter) or prairie dogs.
