[Works on Mobile] Click the breeding structure, then click two eggs. 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 egg! Then you can start breeding all over again until you have them all. You need 3 monsters to unlock the Potbelly egg. You need 7 monsters to unlock the Tweedle egg. You need 18 monsters to unlock the Wubbox egg. You need 19 monsters to unlock the shop. For breeding and incubating, the timer needs to count up to 100 for it to be done. All monsters take the same time. Monsters will take half as long to incubate/breed after waking up the Wubbox. When you power up the Wubbox Egg you can breed all your monsters back. The Wubbox will take all monsters except Noggin, Toe Jammer, Anglow, Jeeode, and Blabbit Egg. There is a 10% chance of getting a rare egg and lower chance of getting an epic egg. If you breed or buy an egg while you already have that monster, it will replace the once you had but it could be a different type (rare, epic, etc.) Once the shop opens, you can select eggs to buy as egg eggs or placed directly onto the island. Some eggs may require you to wait a certain amount of time until they are fully activated on the island. You can hover or hold your finger over a egg to see how much time it has left.
