Zoo Tycoon 2: Unidentified is a User-Made Expansion created by the designing team Cryptid Creators. It started when Murdock and Catboy decided that a lot of good cryptids were missed in Fiction or Reality and that someone should make them if Fantasy Fanatics weren't going to. The first animal that was confirmed for the pack were the Mothman. They always planned on doing 30 Cryptids
ZTU has 8 confirmed animals leaving 22 left animals to reveal.
