Doesn't passive mean that the sheep won't affect other plants at all? I mean if they were "active" they would eat the plants..get what I mean? so the sheep will just be there in the background looking pretty..that's what I think..Also if the sheep ate plants then there should have been an almanac entry for them..right? but there isn't..so the sheep will be "passive" and won't affect any plants..what else do you think "passive" could mean?
