Episode 1 - Small Problems
It was a normal school day and everything was the same. The class was the same, the kids were the same, they were the same age as before. The only thing that was different was Phoebe who came back from her old school because she really missed it here.

The class was talking about creatures that live in molecular size. Wanda doesn't believe if thats true but Dorthy Ann checked in her book and found the results.

Dorthy Ann: According to my research, there are creatures that are microscopic but we can't see them at this distance.

Just then Mrs. Frizzle came through the celling with a announcement

The class: Mrs Frizzle!

Mrs. Frizzle: Good morning class, I have an announcement to make.

Ralphe: We're getting another class pet!?

Joyci: We're having a school party?

Tim: We're having a challenge?

Arnold: Please don't be a field trip?

Mrs. Frizzle: All seem fun but all are incorrect, we are having a new student join us today!

Everyone was excited to hear and Arnold fell back in relief.

Mrs. Frizzle: Speaking of new students here he comes now.

Mrs. Frizzle ran to the door and opened it revealing the student who will be joining the class.

Mrs. Frizzle: Class say hello to our new student and friend, Liz drum roll please.

Liz played the drums revealing the student as he entered the classroom.

Mrs. Frizzle: BEN TENNYSON!

Ben: I hate school.
