Well you can't transform in the water, unless someone could find one of those "underwater air pockets" or w/e, the thing sexyzora found, then maybe. But that's a pretty tiny pond so it's unlikely there would be one there.
Somebody got up there with a Super Jump off a Twilit Keese, don't remember who. After that, it's just a matter of running around and getting to the entrance (good luck with that, since there's no water in the tomb, so you can't swim to it; and even if you could, Wolf Link can't go underwater).
I guess it would have something to do with a power of 2 depending on how Perl handles integer overflow. But that only pertains to the maximum size of a thread, the server capacity is the only thing that matters when it comes to storing this data.
