This plugin enables you to disguise as every mob or as another player.
It is possible to disguise as some non-living mobs as well (e.g. falling blocks).
LibsDisguises is bad - it doesn't morph you to the mob, it turns you invisible and the mob follows you, very bad in 1st person view. Also, it glitches sometimes when walking.
