    public void onCreatureSpawn(CreatureSpawnEvent event) {
        EntityType type = event.getEntityType();
        Entity en = event.getEntity();
        if(event.getLocation().getWorld().getName().equalsIgnoreCase(Hultberg.NORMAL)
        || event.getLocation().getWorld().getName().equalsIgnoreCase(Hultberg.CREATIVE)){
            // Allowed mobs.
            if(type == EntityType.SHEEP
            || type == EntityType.COW
            || type == EntityType.CHICKEN
            || type == EntityType.SQUID
            || type == EntityType.OCELOT
            || type == EntityType.WOLF
            || type == EntityType.MUSHROOM_COW
            || type == EntityType.BAT){
                System.out.println(type.getName() + " spawnet i " + en.getWorld().getName());
                event.setCancelled(false);
            } else {
                System.out.println(type.getName() + " ble ikke spawnet i " + en.getWorld().getName());
                event.setCancelled(true);
            }
        } else if(event.getLocation().getWorld().getName().equalsIgnoreCase(Hultberg.THEEND)){
            // Allowed mobs.
            if(Hultberg.dragonSpawned){
                if(type == EntityType.ENDERMAN
                || type == EntityType.ENDER_DRAGON){
                    event.setCancelled(false);
                } else {
                    event.setCancelled(true);
                }
            } else {
                event.setCancelled(true);
            }
        }
    }

I have been searching for squids in the log for spawning message, but not any message appear.
Anyone know something?

Epic bump.

Anyone?
