Introduction: Minecraft Obstacle Course
Start off with stepping stones on the air so you have to jump to each one.
Next do stairs on cement going up and down for a little twist on the course.
Then make a big square out of glass and put random holes in there to trick them. Since the glass is clear, it is hard to see the holes so they will fall through.
Lastly put stepping stone stairs going down.
End by jumping through a square and your finished!
