Two of my females, a unicorn http://beastkeeper.com/pet/90434 and a dragon http://beastkeeper.com/pet/90435 have statuses listed as "exploring island" for several days now, and I cannot use them for my own exploring.

Is this something that pets sometimes do, or a bug? If it's normal, when might I expect them to come back to active status? Thank you for your time!

First, go to your pets page, then click on Explore tab at the top and it should take you to the island where your pet is. Hope this helps. it happed to me once. :)

That worked, thank you : )

You're Welcome! :)
