Creating a pond in Little Alchemy 2 requires combining several different elements. Firstly, start by combining two Air elements to create Pressure. Then, combine two Earth elements to create Mud. Finally, combine Pressure and Mud to create the Pond element.
Once you have created the Pond element, you can then combine it with various other elements in the game to create a variety of creatures and objects, such as Ducks, Fish, and even a Fountain!
