Making a Swamp in Little Alchemy 2 requires combining several elements together. The basic elements you will need to create a Swamp are Water and Earth.
To begin, start by dragging the Water element onto the playing board. Then, drag the Earth element onto the playing board and combine it with the Water element to create a Mud element.
Next, drag the Mud element onto the playing board. Then, combine it with the Water element to create a Marsh element. Finally, combine the Marsh element with the Earth element to create a Swamp.
Once you have combined all the elements together, you will have successfully created a Swamp in Little Alchemy 2.
