Question about Isle of Tar

[Commander Klaas]

I couldn't find an answer to my question about Isle of Tar, so registering for this forum and searching on Isle of Tar brought me here.
This is what I like to know: how on earth do I get on the platform which leads to the RED gem? I cannot just jump on it (ctrl).

What do you mean you cannot jump on it? It's so easy:

Thanks for that. Now I know that I don't need my pogo to jump on it. Just left+jump. But it isn´t easy, though.
