You are looking for a micro sized bison. When you have found this cache please return it to its hiding place with great care.
As you walk through the woods you will notice trees, logs, branches, sticks and various other sizes of bits of wood. It's a wood... you probably noticed.
... to get to the next cache in the series follow the path, passing through the gate and turning left onto the bridleway leading out of the woods. as you walk demonstrate either your skill, or complete lack thereof, for mimicking any woodland animal (suggest squirrel, deer, gibbon or kangaroo!)
