This is how Princess Celestia releases Trixie, Sunset Shimmer, and Princess Luna's protoplasms goes in
[Princess Celestia gallops to the vat]
Trixie Lulamoon: Celestia. Celestia. Celestia.
Princess Celestia: Trixie. I'll save you.
[Celestia lifts Trixie's soul from the vat]
Trixie Lulamoon: Oh, thanks Celestia. Oh, am I glad to see you. Now let me go so I can return to my body.
[Celestia lets Trixie's protoplasm go]
Trixie Lulamoon: I always knew you were a hero, Celestia.
[Trixie's demon-possessed body prepares to go inside the mansion]
[Trixie's soul heads toward her body]
Trixie Lulamoon: Yahoo!
[Trixie's soul re-enters her body and her neck glows green and a demon pops out of her body]
[The demon roars and prepares to attack when it grows pocks and explodes]
[As the demon disappears into nothingness, Trixie gets an idea]
[Celestia sees Sunset Shimmer's soul and picks it up]
Sunset Shimmer: Celestia can you tell me what happened?
Princess Celestia: Sunset. You're a protoplasmic head.
Sunset Shimmer: I know. But I'm still the wisest protoplasmic head here.
[Celestia lets go of Sunset's protoplasm]
[Sunset's soul screams while flying]
Sunset Shimmer: How do you drive this thing?
Possessed Sunset Shimmer: The ritual is about to be performed. Get everything you can for the ceremony.
Sunset Shimmer: On your right. To the left.
[Sunset's protoplasm tries to re-enter her body]
[Then Sunset's protoplasm bumps into a door and goes bouncing around the room]
[Celestia lifts Princess Luna's soul from the vat]
Princess Luna: Put me back, Celestia. I'll figure a way out myself.
Princess Celestia: How are you going to do that?
Princess Luna: Maybe if I can stretch my tongue, I might be able to get my body back.
[Celestia lets go of Luna's protoplasm]
[Celestia sees the Daemon Ritus on the table]
[Trixie sees the shining suits of armor as she enters the mansion and sees a protoplasm and enters the mansion and sees the possessed Princess Luna]
Trixie Lulamoon: Uh yo yo you yo.
[The possessed Princess Luna walks to Trixie]
[Trixie shoves the possessed Princess Luna over into a room]
Possessed Princess Luna: You'll pay for th...
[The protoplasm enters Luna's body and Luna starts to move around]
[Trixie shuts the door and watches Luna move around]
[Trixie gallops to the window]
[Princess Luna's neck glows green and a demon pops out of her body]
[The demon growls at Princess Luna and starts to attack her]
Trixie Lulamoon: You could use a little sunlight.
[Trixie opens the blindfolds and the demon screams as it explodes]
