From January, 2007:In this new zoo I'll be using all user-created animals, as this zoo has a
volcanic theme. I've never used the lava path (despite having created
it :P), and that's what inspired this zoo. :D Instead of giving a
creative tour, I'll be rating the animals as I go.
Here by the entrance we have the Mythic Salamander (top exhibit) and the
Lavagator (bottom exhibit):

I like the
Mythic Salamander. It requires
solid gray stone, and lava pits, volcanoes and such are habitat neutral,
but it will not tolerate any foliage or rocks, and the highest
suitability I can get it is 81% - with the colorful ferns I put in, the
suitability dropped to 80%.
Conversely, the
Lavagator is one of my
favorite user-created animals ever! They're black gators at first
glance, but glow red around the edges in the water. Lovely exhibit that
needs brown and gray stone, dirt and salt water, as well as some
elevation. Guests absolutely love this animal (I'll get back to you on
the Mythic Salamanders, I forgot to look :P)
When I took this shot, what you see is all there is in the zoo, and
guest happiness had just hit 96%!
To the other side of the entrance you will find Volcanic Unicorns (on
the right) and Pyro Zebras (on the left). Both are programmed to have
volcanoes/tar pits in their exhibits with no effect on their happiness,
making for some interesting exhibits :D

They are programmed closely enough that they can go in a combined
exhibit, but I'm a stickler where exhibit suitability is concerned, so
these 2 exhibits are separated by an invisible fence. Both are crowd
pleasers and a lot of fun! Alternate view of the Volcanic Unis with a
view of the entrance:

Next is the Dragon, or Flying Dragon from ZA. An uninspired shot as far
as photography goes, but you can see that even the babies breathe fire
;)

The highest I could get the suitability for these dragons is in the low
90's, always a point of contention for me, but the animals are happy,
which is always a plus. There's a glitch with this animal that shows
that the preferred foliage is the Baobob tree, when in reality they
prefer a highland exhibit with Himalayan Pine trees, etc.
A couple more shots for you :D These next 2 animals are available at
ZA.
The Eurasian Wyvern is a fun animal, and very nicely done.

You can see the Wyverns in the background here, as well. In the
foreground are my favorite user-created dragon, Lehner's Red Dragon

At first glance this dragon seems a
bit strange, but it has a lovely exhibit (which in this case I tried to
make a bit more natural, which is why you can't see some of them
clearly) and is absolutely adorable. It's the only dragon I've seen
that both walks and flies, and it will suddenly plop onto its side and
curl up for a nap - so cute!
