Description:
There`s a ghoul in Weasley`s attic that is always banging on pipes and making other noise when he feels that things are getting too quiet. You can challenge the ghoul to a game by making some noise of your own!

Instructions:
Each time the ghoul pounds out a pattern, copy his sequence than add an object of your own to the pattern. The only way to quiet the ghoul is to beat him, so you must successfully repeat the growing patterns until he grows tired.
