Script[]
[At Hawk Moth's lair]
Hawk Moth: A firefigher who thinks he's a failure, after his nephew ended up nearly hurt. Such a perfect target for my akuma! [creates an akuma] Fly away, my akuma, and evilize this hero next door! He'll become the new VILLAIN next door! [chuckles]
Ryan Repulsa: Nice one.
[The Akuma flies out the window]
[The Akuma lands on the Syndrome doll. Sam sits upright, as a butterfly frame forms around his eyes]
Hawk Moth: Greetings, Sam-Drome. My name is Hawk Moth. You are no failure; you are the newest superhero in all of Paris. I will give you all the powers of Syndrome, so you will make good on your plans. But, in exchange for these powers, Ryan Repulsa and I will need the Matrix and Ladybug and Cat Noir's Miraculous. Are you up for this task?
Fireman Sam: Yes, Hawk Moth. Sam-Drome hears, and Sam-Drome obeys!
[He lets the Akuma consume him and he becomes Sam-Drome]
Elvis Cridlington: Huh?
Emmet (EG): Who are you?
Sam-Drome: Sam-Drome will not hesitate to introduce himself.
Emmet (EG): Fireman Sam? Did he refer Sam-Drome in third person like Dispair Bear and Retlana?
Sam-Drome: There is no Fireman Sam! There is only Sam-Drome!
[He presses a button on his arm panel and a beam fires at Emmet (EG) hypnotizing him]
Emmet (EG): [clucks like a chicken]
Elvis Cridlington: What did you do to him?
Emmet (EG): Help... me... [clucks]
[Elvis shoots Water on Emmet (EG) freeing him from the hypnotic trace. He runs off]
Sam-Drome: [annoyed] You shouldn't have done that.
[Emmet (EG) finds Marinette]
Emmet (EG): Marinette! Marinette! We got a problem!
Marinette: What's wrong?
Emmet (EG): It's Sam! He's been akumatized!
Tikki: I guess we need to stop him and his hypnosis.
Marinette: Your right, Tikki. Time to transform.
Emmet (EG): I get some water guns.
[Marinette watches as Emmet [EG] dashes off round the corner. She gives A Thumbs Up to Tikki.]
Marinette: Tikki, spots on! Ha!
[Marinette becomes Ladybug]
