The Magic box

Once Billy saw a Magic box. It was blue and red. It had three yellow buttons, two green dials and a red handle. Billy pressed a yellow button. The Magic box opened and there was professor Inkspot in the box. Professor Inkspot closed the lid. Billy pulled the handle. Then, the box opened again but Professor Inkspot wasn't inside. Billy looked inside the box and Professor Inkspot still wasn't there. Billy then knocked on the magic box. Billy pressed the second button. All of a sudden, the box opened. There was Professor Inkspot wearing a clown outfit.
