Tiny Cryptozoology Worlds

Cryptozoology, broken down literally, means the study of hidden animals. Some of the legends of  Cryptozoology include the Sasquatch (Big Foot), the Yeti, and the Loch Ness Monster! There are so many more creatures that can be included in this category,(and oh, we may get to those too!)  but these guys always hold my attention.

So, how appropriate to take these "hidden creatures", and create your own little hidden worlds for them, small enough to carry in your pocket.
