I mainly posted this for kids who build Knex and are familiar with Mario games, because there aren't that many instructables that relate with Knex and Mario. I know it might be kind of confusing, and if you need extra help, just comment. But aside from that, let's get building!

Step 2: Part:2 the Roof
Now you'll be making the roof.
