How do you get things from the wildon creature breeder?

All you have to do is walk around. You might see rare flora, or coins lying around, or even better, a brightly lighted, small tree called the Twilight Vine. It'll never be hidden. Just walk around, and if you're lucky, you'll find it. The twilight vine comes up at, you guessed it, twilight. Coins vary. You could get a thousand farm bucks or maybe even only one. It varies.
