3 Blocks Up

Im trying to have it give you poison 3 blocks above the Monster egg. How would I do so?

Code:

public void onMove2(PlayerMoveEvent e) {
    Player p = e.getPlayer();
    if (e.getTo().getX() == e.getFrom().getX() || e.getTo().getZ() == e.getFrom().getZ()) return;
    Block b = p.getLocation().getBlock().getRelative(BlockFace.DOWN);
    if(b.getType().equals(Material.MONSTER_EGGS)) {
        if (b.getData() != (byte) 2) return;
        if (p.getInventory().getHelmet() != null && p.getInventory().getHelmet().getType().equals(Material.CHAINMAIL_HELMET))
            return;
        p.addPotionEffect(new PotionEffect(PotionEffectType.POISON, 24000, 0), true);
        p.sendMessage(ChatColor.LIGHT_PURPLE + ">> " + ChatColor.WHITE + "Get you Gas Mask on!");

Code:

//Remember: clone is there so you don't mess up the actual eggs location. The "add" method adds those values to the X/Y/Z.
//Also remember that it does not take in negative numbers. If you want to add negative, use ".subtract"
MonsterEgg.getLocation().clone().add(X, Y , Z);
