Butterpear... GRAGHHH!

People probably won't want to tell on this one, but is there a way to get these without logging?

I logged straight for 2 days (about 8 hours, maybe a little more) in the jungles and came back with 6/12. Luckily I have woodworking lvled too so wasn't wasted but without that it totally wasn't worth it, I would say they are likely to be a v.rare result.

I'm wondering if they can be grown as there seem to be people who manage to have a near infinate supply of them. I've been spying and they are never present in the Jungles, although they are online!!

Any clues?
