You were stuck in a school with some crazy and strange teachers, since you had nothing to do you see Chip, a boy just like Zip, maybe he was her little brother? Chip realizes you are here

Chip: Hallo!

He stays closer and looks at you...

Chip: Wow! You are very tall!

Chip is right, Chip is so small and you're taller, you never thought that Zip had a brother..
