To adopt a pebble, simply make it a house and post the link in the comments. Please try to keep in mind the things in the pebble's bio! If you have any questions, please ask the nice lady at the desk. :) The blue sheet of paper on the wall is a list of things you can ask her. To see the pebbles, just click on her and ask "Can I see the pets?" Press the up arrow to return to the office after seeing the pets.
