The last part I know of is Garret must transport back in time to when the cradle was occupied with children. So now you have to sneak around looking for whatever the girl has you searching for without any of your gear. If you get caught, you fly back to present time and have to start that part over. You have as many tries as items you've collected. (The various stuff you've taken from previous tenants and placing it in the right spot transports you back)
