Merge Plants 3D-Garden Defense is a combination of two games: the first one is a classic RPG game and the second one is an idle defense game.

The story of the RPG game is about an evil monster that wants to conquer the world and the only way to stop him is to merge all the plants in the world into one big tree.

In the idle defense game, you have to protect the garden from the zombies. To do that, you have to raise plants and grow them in the garden. When the monsters arrive, you have to fight them and kill them.

To protect the garden, you can use a lot of different types of plants and flowers. However, you need to grow them and nurture them to get them ready for the battle.

You can also use a special kind of plant called a "soul seed" to stop the evil monster. If you can find and collect enough of them, you can use them to stop the monsters.

In the idle defense game, you can also use a special kind of plant to find and collect the "soul seeds".
