Pig Litters
is a small datapack that adds a few suggestions from SimplySarc's "50 Tiny Ways to Improve Minecraft" video. Namely, making pigs more useful by changing them to have litters of 1-6 piglets when bred, and turning rabbits into a bit of a pest (they breed by themselves in litters and uproot carrots). Squid ink giving blindness wasn't in the video, but it's a nice little feature.
