Book 6 of the Breakfast Club Adventures
 
Notes warning students to 'Be nice or be next' start appearing after each incident and soon no one is safe from the goblin’s wrath - not even the Breakfast Club Investigators. As the school descends into chaos, the headteacher threatens to cancel the annual science competition unless the creature is caught. Can Marcus and his friends stop the goblin before it’s too late?
