Warning about Bunny Day in Animal Crossing New Leaf:
Once your town rolls over to bunny day, many rocks will spawn all over your town. This is for the purpose of breaking them to find Stone Eggs to turn in for Zipper T. Bunny’s prizes.
There’s a REALLY high chance that the event will glitch out where the rocks will not be removed the following day, and they’ll turn into normal unbreakable rocks.
So be sure to break all the rocks before the event ends in order to prevent this bug from happening!
I haven’t been able to find anyone with actual evidence that this has happened. I’ve found multiple people who tested this, and all of them found nothing. I was just looking it up yesterday because my mom’s game seemed to be having a glitch where it wasn’t spawning any of the finite eggs (trees, dig spots, rocks). No one online had mentioned anything like this, but plenty of people had passed around this permanent rocks thing, even though people who play ahead to test the game and write guides hadn’t found any evidence of it happening. So don’t live in feeeaarrr
(PS my mom’s problem seemed to be caused by some complications with time travel; she had been jumping ahead a while ago and landed on bunny day by chance, and ended up grabbing a couple stone eggs that she still had with her when she went back to do the event in earnest. We think the game recorded that she’d participated in this bunny day already and just didn’t record how many of each finite egg she got, so it didn’t spawn any.)
