This is how Princess Celestia's spirit thingy goes in

[The story begins in the cave and Princess Celestia is chained to a chair]

Princess Celestia: You snuck up on me, you jerk. Let me out.

[Dark King takes control of the pincer]

[Twilight Sparkle trots closer to see her teacher]

[The pincer reaches for Princess Celestia's soul as it shines a light in her face]

Princess Celestia: This can't be good.

[The pincer gets closer to Princess Celestia's soul]

Princess Celestia: No. No, no, no, no, no.

[The pincer grabs Princess Celestia's soul]

[Dark King pulls the pincer]

Princess Celestia: Oh no. No!

[Twilight watches helplessly as the pincer pulls her teacher's​ soul from her body]

Princess Celestia's soul: [gasps] Hey, put back my spirit thingy. That is so uncool. And you're messing up my hair.

[The pincer sends Princess Celestia's soul to the vat]

Princess Celestia's soul: You're a jerk. Capital J-E--

[Princess Celestia's soul stops speaking as she went into the vat]

[A demon jumps toward Princess Celestia's body and opens her mouth and Princess Celestia's body moves her hooves and the demon goes down Princess Celestia's throat, possessing her body]

[The scene then shifts to Princess Celestia's hair as the demon goes inside her body and possesses her]

[As the demon possesses Princess Celestia's​ body, Princess Celestia's hooves move around. The possessed Princess Celestia awakens]

[The possessed Princess Celestia looks left and right]

Twilight Sparkle: The demon possessed my teacher.

[The footsoldiers arrive at the chair]

[Then the first footsoldier releases the possessed Princess Celestia]

[Then Princess Celestia speaks with a male voice]

Possessed Princess Celestia: Akodu. Mikenopa.

[Then the possessed Princess Celestia, the henchmen, and Dark King leave the cave]

Twilight Sparkle: Trixie.

[Then Twilight Sparkle gallops to the vat]
