Geocache Description:

"I'll be there with bells on! Ho ho!" - Tom Nook

Enjoy a multi-stage puzzle cache that will take you on a nice medium hike (~1-2 miles) in the woods where Tom Nook, CEO of NOOK Inc., likes to relax after a long day of shaking down the villagers of Hidden Pond of their precious bells. The cache IS NOT at the posted coordinates. Unlock the map in the attachment to find your way to Nook's Valley. Make sure to bring a GPS or phone for the required projection for one of the stages.  Please DO NOT REMOVE the stamp or ink pad. These are to remain in the cache so that future finders can stamp their logbooks.
