After being sent to the human world, Emmet comes back as a master builder and goes to the giant black brick where Lord Business is. He then convinces him to be good. In the human world, the kid tells his dad to stop being so serious with Lego. Both work. The things Lord Business kragled are not kragled anymore. But at the very end, weird creatures show up and one says 'We are from the planet Duplo and we are here to destroy you.' Emmet says 'Oh, man.' Then the credits appear.
