The scene begins in Mrs. Johnson's classroom. Students do their math.

Suddenly, the students see a young girl with long pink hair. She is wearing a pink sweater, White skirt (Like Luna's) and little white shoes.

Mrs Johnson: Excuse me girl, are you new here?

? : Yes, I'm starting today. Didn't we tell you?

Mrs. Johnson: No…. Previously, we had a new student ...

? : My name is Jenny Jellyfish. I am in an exchange program.

Madame Johnson: Jenny, you can sit down… (without finishing her sentence, the girl with the pink hair will sit at the desk next to Lincoln.)

Jenny (thought): Cool, I managed to pass myself off as a real human.

The teacher continues her lesson. Lincoln looks at the girl because he has a feeling of knowing her.

The news goes to Lincoln and Clyde's table. She winks at Lincoln.

Jenny: Don't you recognize me Lincoln Loud?

Lincoln: This is the first time ... (She shakes his hand and electrocutes.

Jenny: Sorry when I'm happy my body makes electricity.

Lincoln: Jelly? How? 'Or' What?

Jenny: You see ...

Beginning of the flashback of events before Jelly transforms into a human.

Before Jelly goes to school. The pink jellyfish went to Leni's room to lend some clothes to Leni's mannequins.

Leni suspend her.

Leni: What are you going to do with her clothes?

Jelly: I'll lend them to you.

Leni: Ok. (Leni walks to the door but realizes something) Did you just speak?

Jelly: No…. (The jellyfish is a little hesitant to answer.)

Leni: Ok. (She leaves the room)

Jelly takes the clothes, goes back to Lincoln's room. She transforms into a human, puts on the clothes, and goes to Lincoln's school.

End of flashback.

Clyde: Do you know her?

Lincoln: I ran into her once while walking.

Clyde: Nice to meet you, I'm Clyde.

Jenny: Enchanted.

The ex FBI agent is going to sit down at the table. He spotted seeing the new student with Lincoln and Clyde.

Mr Sci-Fi: A new student? A girl with pink hair with sparks in her hands… Sparks ?! (He picks up his device to identify creatures in space. The screen shows his true form.)

He goes to his office. For shenanigans, a plan.

Mr Sci-Fi: Extraterrestrial to succeed in assimilating by the pupils. I'm going to be able to reveal its existence and the FBI will be able to put me in the space cases section. ( He is laughing. )

He takes an FBI device which keeps it with him.

The scene changes for the class. Jenny, alias Jelly, was marked by the other students. She will amaze everyone with her intelligence.

Jenny was able to become the most popular girl in school in one day. Everybody.

Boy # 1: Jenny, will you go to the movies with me?

Boy # 2: Jenny, do you want to go to the arcade?

Jenny: I don't know what it is but I want to go.

The white haired boy takes Jenny's hand and leads her to a far corner.

Lincoln: What are you doing? If you continue like this, you might get too much attention.

Jenny / Jelly: Relax. It's just a test to see if I can pass myself off as a real human. You saw? Everyone wanted to invite me.

Lincoln: Yeah, I saw it. But you have to be careful.

Jenny / Jelly: Calm down Lincoln, the only way they'll find out I'm an alien in human form is through an x-ray scanner. I don't think humans have invented yet.

Lincoln: Humans invented. Doctors are used to examining the human body.

Jenny / Jelly: What ?! But it is too advanced a technology to be of your level. Without getting upset.

Lincoln: I don't take.

To make the situation worse. The principal announces a compulsory medical examination to the pupils.

Jelly: Lincoln, what's a medical exam?

There the scene changes for the school gymnasium. Nurse Patti was getting her supplies ready.

Nurse Patti: Thank you very much for lending me your x-ray scanner.

Mr Sci-Fi: You're welcome, Nurse Patti. I still have one to prove the existence of aliens.

Nurse Patti: I see ...

All the students are gathered in the school gymnasium for the compulsory medical examination.

Jelly is worried that she is discovered to be an alien.

Jelly: No… No… No… (small electric sparks start to appear in his hands.)

Lincoln: Calm down, Jelly. I'm sure we'll find a solution. I hope so.

The students go through the x-ray one after the other.

The nurse and Mr. Sci-Fi look at each of the results.

Mr Sci-Fi :( thought) I'm sure the alien is among them. With my X-ray scanner, I will be able to discover a hidden alien.

It's Clyde's turn.

Clyde: Easy.

There would remain Lincoln and Jenny. The girl with the pink hair panics more and more and her body begins to be traversed by a lot of electricity.

Nurse Patti: Jenny Jellyfish? Jenny Jellyfish? It's your turn.

Jelly panics the electricity a lot, surrounds her and gets stronger.

Jelly: No! (It unwittingly releases a large magnetic wave that causes a power failure in the school and overheats the device.)

Nurse Patti: Who is it?

Mr Sci-Fi: I don't know, this is the first time such a thing has happened. Maybe it's because of the Pauli effect.

Nurse Patti: Listen to me everyone. That will be all for today, you can go home.

Mr Sci-Fi (thought): Damn, my plan to find an alien is a failure. I'm sure he will have more opportunities to prove the existence of people from outer space.

The students go home. Jelly transforms into Medusa and floats near Lincoln.

Clyde: Your jellyfish is here. Hey where's Jenny?

Lincoln: She walked in. This house is on the other side of town.

Clyde: Ok. It is really great. (The two separate.)

The scene changes to Lincoln's bedroom.

Lincoln: We have to be more careful. If you hadn't caused a power failure. Your secret will be revealed.

Jelly: Yeah, you're right. I have to listen to you more often.

Leni came to Lincoln's room with a couple of muffins.

Leni: Lincoln, daddy made muffins. (She hands her little brother.)

Lincoln: Thanks, Leni.

Jelly: Oh are these mushrooms?

Leni: Did your jellyfish just speak?

Jelly: No ...

Leni: Ok. (Leaving).
