Well, every question on ZA should start with one action and that action is to NOT start a new topic right away. Before you do ANYTHING else, you should always check to see if your question has already been answered (and 9 times out of 10, it has). Luckily, one of our staff members was kind enough to write up a tutorial on how to use the search feature on this website, and you can find that tutorial
HERE.
Also, both Budgie and SageofWater are correct...try using the VAT which is to date the best varient making guide that we or Zoo Tycoon 2 Designing Centre have. The ZT2DC is a site that can be found
HERE and is the only site devoted solely to creating animals, skins, objects, foliage, everything, for ZT2.
