Lego Lord of the Rings -
Extinguishing this fire will require the two hobbits to cooperate. Choose Frodo, jump along the leaves onto a small island and press the button there. It will activate a nearby pond - now just switch back to Sam, fill up the bucket and extinguish the fire. You need to be fast here, as if you will hesitate with pressing (K) for too long, you Hobbit will drown. After you extinguish the fire, you will be able to move on.
