Minecraft for X-Box 360

I built a house in creative mode out of wool and stained glass and my floor is wood. I also have iron doors, but somehow zombie, creepers, and spiders are still popping up in my house. Is this because I'm in creative or can they break through the wool. Someone please help me!

Is it lit up properly? Monsters spawn in darkness, even a little bit of darkness can cause them to spawn at night, sometimes you have to put an ugly torch on the floor instead of the walls as the light radius doesn't quite reach the centre of the room

Zombies can spawn anywhere, but if there's light then they can't spawn there. Try glowstone blocks or torches.

Just add a bloody torch or two

What side did you place the door on? I used to place the doors from the inside. You must also install Leo Privacy Guard to your smart phone, Keep snoopers away from private pics, videos, SMS and call log.
