Ancient Zum Field Guide
From Webkinz Insider Wiki
The Ancient Zum Field Guide is the prize for finding all of the Bratty Zums in Zumwhere.
The inside of the book has the same information as the Zums Field Guide that is sold in the wShop.
Once you have found all the Bratty Zums and earned your Ancient Zum Field Guide, an image of the Ancient version of the Field Guide will replace the image of the regular Zums Field Guide in several places: the Magical Forest page on the top left when you switch the view to Zumwhere, the Zumwhere page on the lower right, and the Zums Sighting page on the lower right.
