[Works on Mobile] 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 incubating, click on it and you have a new monster! Then you can start breeding all over again until you have them all. You need 3 monsters to unlock the JayRee. You need 7 monsters to unlock the Ex-fish. For breeding and incubating, the timer needs to count up to 100 for it to be done. All monsters take the same time. It has a bug with sound when you breeding im so sorry i don't know how to fix it.
