I noticed that some of the eggplants in Bonelington Hole randomly go from small to large to small to large every couple of seconds (randomly); it might be because I'm on an old (probably unsupported) version of Firefox (see below) but it looks pretty buggy-- might be worth checking out (I haven't noticed on my other computer which has Chrome and an updated OS-- also haven't noticed it in any other strees other than Bonelington).
