I don't know what I did to make them Explore this Island but I want them to stop now :'(

What did I do to make my pets start Exploring Island and how do I get them to stop?

Are you having difficulty getting your pet OFF the Island? If so, walk your pet to the portal. When said pet is ON the portal an egg shaped swirl will appear in the portal pictured UNDER the directional arrows to the side. These arrows are what you use to guide your pet around the Island. When the egg swirl appears, click on it. You should get a box above the the Island asking if you're sure you want to leave. Click yes and your pet SHOULD be off the Island!
