We All Live in a Paper Submarine.

Sorry, I remember now, it was a Yellow Submarine;

        I have this Sub that is making me think the Cidade-Del Rio is going to be a pushover to build. Yeah, I have used a lot of different scratch skills, But I don't believe the sub will allow that.

       It has so many teensy constructs that I could use probably build all day and never see the same part again! Plus, it's very colorful!

Still cannot figure out what the drill looking nose is for .The deck gear doesn't allow for that structure to stick up if the thing is supposed to do tunnels? We'll see!
