Is There Wood in a Structure?

Wood was one of the elements that we needed, but I don't know if that would have anything to do with his tea. The only buildings you see nearby is like maybe some foggy structures on the other side of the can. Is there an across walk or like some way to get over there? Or is it jumping distance? It's about 10 feet wide. Please don't let him do this. This is a magma pool at the bottom if you don't make it.
