This is how
They arrived in Bricksburg
Ryan: Bricksburg! It's great to be here!
Matau: It's been so long, since we left this world.
Bertram: I wonder how Wyldstyle, Emmet and the others are doing?
Sci-Ryan: Don't know. Let's go see them.
They heard screaming at the City
Ryan: Oh no, something up.
They went off to Investigate and they saw Lord Business Robots attacking the People
Emmet: There's too many of them!?
Wyldstyle: Help us!
Then Ryan and his friends appeared
Sora: We have to get rid of them!
Ryan: We have to keep the People away from those Robots!
They are fighting them and they defeated them
Ryan: Man, that was close.
Emmet: Thank goodness, you're back. And we have trouble in Bricksburg, Lord Business is attacking so the People and Master Builder in Bricksburg.
Sora: What happened?
Emmet: Don't know, Lord Business is planning on something else. And we have to find out of what his planning. And we go to that Tower and Stop him.
Ryan: Ok. Sora and I can handle it.
They went off and they saw Lord Business
Lord Business: Well, look who decided to show up.
Benny: Lord Business!
Unikitty: We can't let you take over the city!
Donald: And you have us to deal with!
They are fighting him and they defeated him
Ryan: If you trick us for reforming you, I'll whack you with my Keyblade. Got it!
Lord Business: Okay, I will!
Ryan: Good. That's more like it.
Emmet: Ryan. I got the Piece of Resistance on my back.
Ryan: Let me get it off.
And then it's glowing, Ryan and Sora unlock a New Gateway
Ryan: At least we can go now. Emmet? Is anything I can do if I can find Cody?
Emmet: Well, Ryan. The only way to find Cody, is to beleave you can. I think that's something from a cat poster.
Sora: Don't worry, we'll come back.
They left this world
