It's five miles. Though if I went to another island...ugh, she'd never let me out of her sight afterwards, but I can't hide quite yet. [Had to find Haibara. Had to warn HER about this.]

I'm not looking to cheat. Especially with all the hints you've already given. Just the red and perspective will probably help a great deal.

Only the food that's not weird. I don't eat anything like cake growing from a tree, but the things that grow like they should. It might be something was added that's not usually there.
