If anyone needs this annoying achievement, message me or post here, I have a world set specifically for it. I have a pig captured and a saddle ready, so it should only take you one try to get the achievement.
40G | When Pigs Fly - Use a saddle to ride a pig, then have the pig get hurt from fall damage while riding it.
I've helped over a dozen people earn this achievement today and will be helping more people tomorrow night around 10PM EST. If anyone else wants this pain in the butt achievement then please message me or send me a friend request, but please mention When
Pigs Fly so I know why you're messaging/friend requesting me.
I can also help with the cake and bread achievements as well.
