So Gollum, in his boredom and using the One Ring, stole materials from the Goblins that he might sail the seven seas of his lake inside a cave. What did he even need the boat for? Hauling up his big catch? Hunting Moby Dick?
Was it like a ferry that he used to go to and fro from his island, and also a security feature that kept the Goblins from sailing over to find him? The more I think about it, the more hokey it all sounds (but the Hobbit is a little odd anyway).
And I care. My day hinges on this issue...
