Desert Island Risks

If you were left on a desert island, what three things would you take along?

Oh, I get it--this is like all those cartoons you see with someone stranded on an asteroid, isn't it? Can I say a flyer, plenty of fuel, and a good map showing how to get home?

No, I didn't think so.

All right then, I'll say a teleport bracelet so I can call for help and hope someone comes and gets me, a torch so I can see what I'm scared of, and a portable force-field generator so I can keep all the things I'm scared of away from me, especially when I'm having a nap.

And this had better not be Chenga. I'm attached to all my bits, thank you very much.
