During a routine day in Castle Frank N. Stein, Head was sent flying down a staircase when Chuck D. Head tried to throw him at Igor. The skull bumped into a bottle and released the cork, allowing Peter to escape. Head explained to Peter about Igor's nastiness, so Peter decided to help him. With just a wink, Peter managed to turn Igor into the nicest person ever. Peter stuck around to witness the aftermath of Igor's transformation, watching with glee as the castle's residents struggled to come to terms with what was happening.
