To make a campfire in Little Alchemy 2, you will need to combine the following elements: wood, fire, and a match. First, combine wood and fire to create an open fire. Then, add the match to your open fire to make a campfire. This is the most basic way to make a campfire in the game. However, you may also combine a tree stump and an open fire to get a campfire. You can also combine an ax and a tree to create a tree stump and a campfire in one go. Experiment with different combinations of elements to find the best way to make a campfire in the game. Happy playing!
