Merge Animals is a little Tower Defense game in which you will have to interact with different animals to block the invaders who will try to seize their kingdom. To acquire the different animals that will constitute your defense, click on the &quot;Random Pet&quot; button when your budget allows it. Animals with the same number can be combined, which will increase their strike force. You also have the option to upgrade each animal through the Shop, which is highly recommended for you to achieve victory!
