We get introduced to Peter, Susan, and Duncan. Duncan is the bully and he throws Peter's book in a puddle.
Mr. Smith/ Broxholm
Susan's normal teacher, Ms. Schwartz is gone and there is a new teacher for now named, Mr. Smith. Susan doesn't like him and writes a sticky note on her test to give it to her friend, Stacy saying Mr. Smith is a total creepazoid, He has totally ruined this class. Our whole year has gone down the tubes. The man is a total philistine! but, Mr. Smith collects her test with the sticky note.
Susan follows Mr. Smith home to get the sticky note, then hears a horrible sound sounding like a cat in a blender and she goes into his house to find out Mr. Smith is an alien named Broxholm.
Susan and the whole band play their instruments which hurts Broxholm because, of the music and he takes his mask off on Susan's command.
Peter helps Broxholm ESCAPE! They go to his house and fly off in a UFO.
Susan goes into Broxholm's house after the police check it and she sees if Ms. Schwartz is okay, since Broxholm trapped her in a force field. She find Ms. Schwartz out of the force field and saying "This is the worst headache I have ever had!" They cry on the floor together hugging.
