Help using Remote Entities

So I made RemoteEntity spawn with a 1/15 chance of hitting a regular mob. How can I make it so it only makes a sound when it is a special entity? I've tried to use hashmaps, here's my code:

Code:java

    @EventHandler
    public void onDamage(EntityDamageByEntityEvent e){
        if(e.getDamager() instanceof Player && e.getEntity() instanceof Pig){
            int r = gen.nextInt(15);
 
            Pig pig = (Pig) e.getEntity();   
                LivingEntity li = (LivingEntity) e.getDamager();
                if(special.get(pig) == null){
                    special.put(pig, false);
                }
                if(special.get(pig) !=null){
                    if(special.get(pig).equals(true)){
                        pig.getWorld().playSound(pig.getLocation(), Sound.GHAST_SCREAM, 3F, 7F);
                        return;
                    }
 
                }
                if(r < 15){
 
 
 
                EntityManager manager = RemoteEntities.createManager(this);
                    RemoteEntity entity = manager.createEntity(RemoteEntityType.Pig, pig.getLocation(), false);
                        //entity.getMind().addTargetingDesire(new DesireFindAttackingTarget(50F, true, false), 5);
                        //entity.getMind().addMovementDesire(new DesireMoveAndMeleeAttack(Player.class, true), 4);
                    entity.getMind().addMovementDesire(new DesireKillTarget(li), 4);
                        special.put((Entity) entity, true);
 
                    pig.setHealth(5.0);
                    pig.remove();

Sorry if I worded it a bit confusing but essentially I want it to only make ghast noises when it is a special mob but right now it doesn't do anything. Thanks!
