Here is the transcript for Ash's Adventures of Scooby-Doo on Zombie Island.
Opening
(The film opens on a rainy night at a haunted castle and the title reads "Ash's Adventures of Scooby-Doo on Zombie Island" appears and we see inside the castle as the credits role till we zoom into a door, until a monster tears the doors open and got to Mystery Inc. and Fred, Daphne, and Velma run to the left. Shaggy and Scooby screams and they run different directions)
Shaggy Rogers: YIKES!!!
(He goes to a room, lock the door behind him and goes to the other door to get away the monster was in front of the door and Shaggy tries to get out the door he locked but he pulls out the doorknob and he runs off)
Shaggy Rogers: Scooby-Doo! Where are you?!
(He runs and bumps into Scooby, then "Scooby-Doo! Where Are You" plays)
Scooby-Dooby-Doo, where are you?
We got some work to do now.
Scooby-Dooby-Doo, where are you?
We need some help from you now.
Come on, Scooby-Doo,
I see you,
pretending you got a sliver.
But you're not fooling me,
'cause I can see,
the way you shake and shiver.
You know we got a mystery to solve,
so Scooby-Doo, be ready for your act.
Don't hold back!
And, Scooby-Doo, if you come through,
you're going to have yourself a Scooby Snack!
That's a fact!
Scooby-Dooby-Doo, here are you.
You're ready and you're willing.
If we can count on you, Scooby-Doo,
I know we'll catch that villain.
(Then, Scooby lands on the empty knight's armor and the rest fall like dominoes and one land on the moat monster. Shaggy and Fred help Velma and Daphne up and Velma unmasks the monster)
Shaggy Rogers: Like, it's Mr. Beeman, the real estate agent.
Scooby-Doo: Mr. Beeman?
Velma Dinkley: Yeah, he was printing millions of counterfeit dollars in the basement with his printing press. What we originally thought was mold was really green ink. See?
Mr. Beeman: I would've gotten away with it, too, if it wasn't for that big dog and you meddling kids!
(Scooby gets the mask and but then scares himself)

Airport boss: You're a couple of Gorgonzolas! You're fired!
(He leaves angerly and slams the door)

Simone Lenoir (V.O.): We enter the curse of the pirates... to destroy them as they had destroyed our island. Our wish was granted.
(Now we go to Moonscar and his pirates are digging the hole preparing to put the chest inside the hole as they see Simone and Lena in their werecats forms)
Simone Lenoir (V.O.): We became cat creatures and destroyed the pirates.
(Moonscar screams as flasback ends)

Simone Lenoir (V.O.): At least until the harvest moon.
(The man screams seeing the cat creatures then flashback ends again)
Simone Lenoir: Sometimes it became necessary for Lena to lure outsiders back to the island.
Fred Jones: Just like you lured us.
Lena Dupree: I had years of practice.
Daphne Blake: And those zombies are just the poor souls you drained. They were just trying to warn us, so we won't suffer the same fate, they did.
