you need to bring him water sold by the gorons in the south part of town. In order for them to have the water, you need to have beaten the temple in death mountain. One of the goron elders will be down by malo's shop, and he'll give you the quest to deliver the water. once you do, you can bring water to the goron, which will give him strength to finish his task.
After you invest 1000 rupees in Malo Mart in Kakariko, go talk to the Goron outside and do the water running quest, run the water to the west bridge and throw it on the lazy goron. The water will rejuvinate the goron and he will fix the bridge. Then when you go into the market town, A new malo mart will be opened there. Go inside and you can purchase it for 500-600 rupees i think...
First talk to the Goron; Then Z-target and throw using A. I had trouble with this part too. Hope I helped in some way. (Plus you get the water in the big tub, not in the bottle.) Now if you are talking about the Goron outside Hyrule Castle; I THINK...... You Z-target and push B to and him the warm water. Or, talk to him and he will ask for it. But, you must help the other Goron set up a shop in Castle Town before you do this task.
