Here's a fun forest idea for a party: make a shot glass tree! Use whiskey and a green spirit such as midori or absinthe to create a stump and a coniferous treetop! (To tell you the truth, I couldn't afford all that and didn't really want to drink a ton of hard alcohol, so I just used beer and food coloring!) This idea would work very well for a christmas party, too! Play a drinking game with the shots where party guests have to answer trivia questions about the forest to win a shot!
