High School DaysEdit
During a normal school day, Marco Diaz was called to the principal's office. Hoping to get into trouble for once, Marco was disappointed to learn that he was just chosen by Al Mualim to guide the new foreign exchange student, Star Butterfly. As the disgruntled Marco shows Star around Nintendo High School, he mentions that he would like a little danger in his life. Star obliges by using her wand to turn a butterfly into a screeching winged monster. After Star tells him who she is, Marco, frightened by Star, declares the tour over and runs away from her.
