fresian_horse, howdy! It's nice to meet you! Yes, there was quite a discussion on the 'ghost' animals. If you've read the post - that's it. It was the only time we discussed it. They ARE there, but none of us could come to a definite conclusion as to whether they were glitches or easter eggs. (An easter egg is a surprise put in by a gnome-y programmer, who wants to see how long it'll take us to find them). There are a handful in ZT2/ES. The 'ghosts' MAY be one of them - no one really knows.
Now that you've met ME, go on over to Introductions and meet everyone else! You'll find that there are a lot of interesting discussions here besides "the ghoulies and ghosties and long-leggitty beasties"! :lol
And, since there IS a topic on this, I'm going to close this one.
