In ALBW (and most other Zelda games), Link likes to mow down grass, but don't press B too quickly or a golden bee might be lost!
I've read online that this happened to some unfortunate people. As for me, I did find a golden bee while cutting grass...but it got away because I kept recatching the regular bee that I released from my bottle in order to make room for the golden bee...(<-wow, run-on). Well, that didn't really matter 'cause you can buy one for 888 rupees later on
Yeah, it looks like Link has been cutting the same grass all day long.
