First off, thanks to Itzz Sh0wt1m3
for making so many worlds for Minecraft and zzUrbanSpaceman
for his solution for this in Minecraft Achievements
What I did was combine the two because when when I was using Itzz Sh0wt1m3
's world, I couldn't get the pig to go over the edge. Load up Itzz Sh0wt1m3
's world and do the following:
When you spawn in, use the blocks in your inventory to trap the pig in a 1X2 block space at the end of the trench farthest from the pit you are meant to ride the pig off. Do this by placing one block at the top of the trench first, or the pig will use it to escape. Place the second block below that.
Now that the pig is trapped, break out the wall of the trench and dig down four blocks, then dig out three blocks below where the pig is standing leaving one level of blocks directly below the pig and a three block deep pit below that. Go back to where you started so that you are not below the pig's two blocks and dig yourself out of your newly dug pit.
Place one block to the side of your small pig pen and climb over into the 1X2 pen with the pig. Saddle the pig and mount him. Finally, dig out the dirt block directly below the pig and drop three blocks unlocking the achievement.
