Thats a pretty cool Christmas decoration.
Solve puzzles with angry chickens in the house!
Here is a more hardcore version of Christmas lights to the beat of music by Slayer.
Here is another house set up with a sweet Christmas light display synced up with music.
Possess items around the house and scare everyone out! The more you scare, the more powerful you become. Don't frighten them too much though, they might freak out and do something stupid...
Help FireBoy and WaterGirl in this new adventure! Control both characters at the same time to solve platformer puzzles! Direct light beams to the sensors using different kinds of mirrors, activate buttons and levers to move platforms, push boxes and roll balls, collect all the diamonds and get each character to his door!
In case you need some more light.
That looks like a tastey house.
Now that is what you call a tree house.
