Another downfall for Oogie Boogie/Battling Grogar, Bill and the Dark Lords

Here is how the fight agains the Legion of Doom begins in Welcome to HorrorLand.

At Oogie Boogie's lair, Yuna and her friends fought a great Halloween battle.

Princess Yuna: That's all of them.

Princess Susan: So long, Monsters!

K.I.T.T.: (as Ecto-88) My scanner says that Johnathan Chiller is in danger.

Princess Solarna: Who?

Savannah Meades: He's our friend, and he needs our help.

Then, they came just in time to the rescue.

Oogie Boogie: Time's up, Kiddies.

As Oogie throws the dice into the skull, they came out with a pair of snake eyes.

Oogie Boogie: What, snake eyes?!

Princess Yuna: Hey, Jack. You deal with Oogie while we go and save Johnathan Chiller.

Jack Skellington: Be careful, Yuna.

Princess Yuna: I will.

Yuna and her friends sneak into the lair, while Jack goes to battle with Oogie.

Oogie Boogie: Any last words, Chill Man?

Johnathan Chiller: You'll never get away with this!

Oogie Boogie: Too late, Chill Man. I just did. Bye-bye, Chill Man. (evilly laughed but stopped) What the?

Just as Yuna and her friends rescued Johnathan Chiller, Jack appeared in front of him.

Jack Skellington: Hello, Oogie.

Oogie Boogie: (gasp) Jack, I thought you wouldn't be here in HorrorLand when you're all chopped up!

Just as a bunch of Evil Knights surrounded Jack Skellington, he'd fought them one by one and against Jack.

Oogie Boogie: Wanna meet my cowpoke, Princess!?

Princess Yuna: I've met plenty, Oogie!

Oogie Boogie: Ooooh!

Oogie stepped on the button, the robotic cowboys aimed his guns.

Oogie Boogie: FIRE!

Jack came up to Oogie, he dodged him.

Oogie Boogie: Miss me, Jack!

Oogie ran for his life, Yuna loosened up his string.

Princess Solarna: Yuna, Jack, watch out!

After that, the Body Squeezers fired their freeze ray gun at Jack Skellington as he dodged it.

Jack Skellington: It's over for you, Oogie!

Oogie Boogie: So long, Jack! (evilly laughs)

Jack Skellington: How dare you treat my friends so shamefully!

With quick thinking, Yuna bust open Oogie's stitches making his bugs coming out of him.

Oogie Boogie: Now, look what you've done! My bugs! My bugs! My bugs! My bugs! My bugs! My bugs! My bugs!

Then, the very last bug was squashed by Hadji with his foot.

Princess Skyla: I really hated bugs.

Princess Yuna: Now, to find and put a stop to Grogar, Bill Cipher and their gang for good.

The Sorceress: Going somewhere?

Then, the Mutant Plants used their vines to rap Princess Yuna and her friends tight.

Cosmo the Seedrian: Back off!

Princess Susan: Not again!

Princess Yuna: I've seen plants like these before. (disintegrated them with her magic) But not magic proof enough.

Ripto: What!?

Gnasty Gnorc: Impossible!

Princess Flurry Heart: (magically trapping them) Now, you can't escape!

Mei Lee: (uses her force to retrieve her lightsaber and ignites it) It’s over!

Ripto: I look back if I were you, Princess Flurry Heart!

The Sorceress: Surprise!

Princess Susan: Uh-oh.

Princess Flurry Heart: Sorceress!

The Sorceress: You’re mine now!

Then, she started blasting Flurry Heart as she magically teleported away from her.

K.I.T.T.: (as Ecto-88) You missed!

Gnasty Gnorc: Not again!

Princess Solarna: Yes that again, Gnasty Gnorc!

Solarna and Hadji fought off Gnasty Gnorc, Ripto and the Sorceress, it was a long battle.

Ripto: You think you can win?

Lord Nooth: Get them!

Scootaloo (Human): (shocks Goobot)

King Goobot: AAAAAAAAAHHHHHHHH!!!

Scootaloo (Human): Serves you right, Goobot!

Professor Calamitous: They're too powerful, Grogar!

Nightmare Moon: Who cares, they're not a big deal to me!

Princess Yuna: How about now?

Grogar: What is this?!

Dark Sombra: I don't know!

Then, Yuna came up with just an idea.

Princess Yuna: Now, Susan!

Susan uses her slingshot at the Toad, it was a direct hit.

The Toad: (got knocked out)

Princess Susan: Bullseye!

Jim Lake Jr.: Now, Yuna! Work your spell!!

As Yuna worked her magic, Grogar, Bill Cipher and the Dark Lords were turned to stone.

Negaduck: We better retreat.

But then, Other Chris and Other Meg blocked the villains path from escaping.

Dipper Pines: Don't even try it, Negaduck.

Negaduck: Are you kidding me!?

Ecto-88 deploys some cages for the villains, they had nowhere else to go.

Lord Nooth: Not again!

King Goobot: We're trapped!

Johnathan Chiller: You don't have much time, Yuna. (give Yuna the Goosebumps Manuscript) Take this manuscript, it'll trap every last monster from Goosebumps including Slappy.

Princess Yuna: Thanks, Johnathan. Can you, Will, Other Chris, and Other Meg make sure the Fearsome Five and League of Villains don't escape.

Johnathan Chiller: Of course, Princess Yuna. Now go, be careful, and good luck to you young ones.

Honker Muddlefoot: Thanks, Mr. Chiller.

Princess Velvet Sentry: We'll be alright.

So with that, Yuna and her friends set off to stop Slappy and the Goosebumps Monsters.
