So, here is what I will do to retool the Aussie area once the DLC comes out.
-the PINK area will be the Red kangaroo. not much to change out here except the plants and scenery.
-The orange area in the lower-right was going to be a small animal house of sorts, but will now be the home to the koalas.
-The red area will remain unchanged except for a scenery upgrade. I will also swap out one of the exhibits to house the new lizard, but these houses are really designed in the plan to be bird houses.
-The light-blue triangle in the upper-right was going to be the emu, but will now be the cassowary. Not much to change here except plants and scenery.
-The lime-green areas on either side of the main house is the biggest change. it was two separate habitats...one for wallaby, the other for wombats, but now I will combine them...with a connecting tunnel under part of the house, and this will be for the dingo.
-The two yellow circles are still the staff backstage areas.
-The tan square in the house was going to be fruit bats, but need to figure out what to do with this.
-The white area was also for a small mammal if they provided one (like echidna or Tas Devil), but now I may just scratch this one all together and reconfigure to just be a garden area or something.
