[Works on Mobile] Click the map icon to breed monsters on outer islands. Once you transpose enough monsters you can start breeding them. Click the breeding structure, then click two monsters. Wait for the monster you bred. Click on it once it has bred then wait for it in the nursery. Once it's done in the nursery, click on it and you have a new monster! Then you can start breeding all over again until you have them all. For breeding and nursery, the timer needs to count up to 100 for it to be done.
