Bonobo loves swinging from cache to cache in search of forest and woodland caches. All Cache Buddies are made of aluminum, just like travel bugs, and come with a chain so that it may be attached to another item. Bonobo the Monkey measures just under 2".
Each trackable has its own page on geocaching.com where you can track its progress as it passes from person to person or cache to cache. Or make your friends jealous when you let them discover it at events!
