I got nothing from fruit trees or dead trees. Royal cows drop orange butterflies but none so far from the purple cow. My drop rate from regular cows is 1 or 2 out 7.
Also, has anyone noticed that the value pack offers 60 yellow butterflies (the ones that drop from Ivy’s hut)? If we need at least 60 of those butterflies for the event, ivy better be a guaranteed multi drop!
