For bonus animals:
1. Unzip the *.ZTD file, I’ll use the antelope.ZTD.
2. Create an animal on APE. It doesn’t matter what, you just want the *.UCA file. Unzip this animal’s *.ZTD.
3. Copy the *.UCA file (inside the animals folder, it will be named with numbers and letters, i.e. BF84C912.UCA) from the animal you created into the animals folder for the sable antelope.
4. Using Wordpad, open the *.UCA file and delete all text.
5. Using Wordpad, open the sablea.ai. Copy all text and paste it into the *.UCA file.
6. Delete the sablea.ai file and rename the *.UCA file to sablea.UCA.
7. Zip the animal back up as a *. ZTD file and it is available in APE.
For dinos and sea creatures:
1. Unzip the animals5.ZTD, animals6.ZTD, animals8.ZTD, animals9.ZTD and animalsa.ZTD files.
2. Create a new folder, name it animals.
3. Inside the animals folder, create another new folder. Name it with the same name as the *.ai file of the animal you are extracting. I’ll use the allosaurus. The AI file is allo.ai, so name the folder allo.
4. Copy the allo.ai file from the unzipped animals8 folder into the animals folder with the allo folder.
5. In the unzipped animals5 folder, there is an allo folder. Copy the m folder, y folder and and allo.pal file into the allo folder (the one that you created in your animals folder).
6. In the unzipped animals6 folder, there is also an allo folder. Copy the icmallo, lsmallo, plmallo and the wave files into the allo folder (the one that you created in your animals folder).
7. Switch the AI file to a UCA file as described above for the sable antelope.
8. Zip up the creature as a*.ZTD file and it is available in APE.
For MM creatures, the files you need are in the animals9.ZTD and the animalsa.ZTD. It works just as well, but I haven’t tried to do anything with any of the MM creatures beyond this.
Any new animal created this way will overwrite the animal you are extracting the animations from, so in order to use the animations you need to save them and reload them in APE with a new animal you are creating, using an animal that APE provides access to. This poses problems in terms of AI with some behaviors and the corresponding animations, and may require editing in the UCA file to get the animal to work properly. This method will allow you to look at compatability, behaviors and all other properties, so you can record these and transfer them to the animal you’ve created. It also pulls the sounds into APE. I’ve been trying to work out a way where these animals can be used in APE directly, but I haven’t figured out how to do it yet.
Hope this helps.
It Doesn't work i treid a million times i give up AHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 
- yep theres definately a theme here.... (to be continued) 
or a wmv file? i gotta see it first then i might beable to understand more? all the words after awhile look like dots?
I'm not even gonna try.
I think I have it figured out and stuff though......
I’m a whale addict, you know. And my favorite species are – yep, the Orcas. They were the main reason I started playing ZT and experimenting with APE, because it’s such a temptation to become the owner of an orca, even if it’s just virtual.
