There is a field with Nintenman[1] on the left, and a large turtle (which looks very similar to Bowser) on the right. The large turtle will either kick rocks or spit flames at Nintenman. The players must use the button to jump over the rocks, and the to duck under the flames.
1st difficulty level: The player must jump over one rock.
2nd difficulty level: The player must either duck under the turtle's flames or jump over two rocks.
3rd difficulty level: The player must either duck under the flames or jump over three rocks.
