I think I managed to figure out the elephants on the third try.
I'm not sure about the license; it's version 1.5.
The point is that if you run there too early (sometime before the end of the first week) or too late (after the second week), you can't do anything – the elephants just stand there. And you can't run straight up either; otherwise, the elephant will also stop. I managed to pass when I first went down and then quickly ran up to the left edge; then, the elephant went down, and I passed. If you go in some other way, the elephant gets stuck (probably forever – I didn't wait for more than 2-2.5 weeks) in that place – maybe it's some kind of bug, or maybe it's just some inconsistencies between the game and my hardware.
