Runt Higgins has a long to-do list. He needs to find out who cursed him, and why; he needs to make up with his best friend, Syke; and he needs to pass the Junior Henchman Training Program. That last one? Not likely. Professor Murphy hates Runt and is actively trying to fail him. The only way for Runt to pass the class and stay at Dr. Critchlore's school is to locate a rare mineral that Dr. Critchlore needs to make an Undefeatable Minion. To find it, Runt must travel to icy Upper Worb and battle gyrfalcons, yetis . . . and the loathsome team from Dr. Pravus's school. Their newest member? Runt's former best friend, Syke.
