Cryptid Creators is a user-made expansion pack group(abreviated as CC) created, by Murdock129 and Caterboy(Cheetor/Cryptidzookeeper), in 2008. They told people about it at Zoo Tycoon Volcano. Most of the members originate from there.
For the first month or so the group had no forum, but then Murdock129 out the Zoo Tycoon Mystery League. The group has only been around for a short time but has already had several members leave; MAD HEAD, cybertiger and Z-master and Blizzardbat and Coolcon55 have all joined and then left.
