Bob-Ball

In the skies, a Bob-Ball (which is a sub-species of a Bob-Omb) found a magical bar, that can move and contains a spring inside. The Bob-Ball decided to clear up brick blocks (which have been floating at the sky for too long), with the help of the magical bar. However, someone has set a timer on the Bob-Ball without any reason, so the Bob-Ball can't be breaking the brick blocks forever.
