Chapter 1:
Once upon a time, there was a king named King Mickey. He ruled over a large and wonderful kingdom. The crops grew bout less and plentiful and the birds all sing happy tunes.
The Bird sings an Oh Boys Song.
Everything was just as wonderful as it can be, until an evil usurper ambushed The King.
"Ambush," says Glomgold as he hits Mickey in the head.
He took the throne after throwing King Mickey into the Cave of Amnesia. From that day forward, things in the Kingdom changed. Not to mention, the only way to get food was to pay the King in compliments.
"Oh, Great King, you're the most handsome and dashing duck in the world!"
"Give him some slop," says Glomgold.
"Oh, Great King, your beard is like a gray lion's mane..."
"Are you saying I'm old? Banish her from the Kingdom!"
The woman's put on a catapult and launched out.
But there were two subjects of the King that dare to challenge his authority.
"Hey," says Donald, "this slop is too cold!"
"I can't understand him," says Goofy.
"Your soup's not cold," says Glomgold, who then snaps his fingers.
The guard then pours the soup on Donald's head.
"It's on your head!" Glomgold then laughs. "Are you not entertained?"
"No." Donald takes Glomgold's pants. "But they are."
The people laugh at Glomgold.
"You know what we do to pant thieves around here?"
"Give them a strong verbal warning and let them go free?"
"I cannae understand you, but I'm going to throw you in the dungeon! Minion!"
Donald and Goofy are thrown in the dungeon.
"You can't do this to us!"
"Gosh," says Goofy, "if only King Mickey were here."
"That's why we're going to break out of here and go on a quest to find him."
"You two are wasting your time," says a prisoner, "there's no way out of this dungeon. I've been down here for ten years."
"But Glomgold hasn' been in command for that long," says Goofy.
"I'm in here for a real crime," says the prisoner, "stalking attractive ladies and making them uncomfortable. But it's not so bad in here. The food's actually pretty good."
"Is he eatin' a bug," asks Goofy.
"Yes, he is," says Donald.
"I gots me an idea," says Goofy.
...
"B-1," says Guard-1.
"Bingo," says Guard-2.
"Help," says Donald, "this dog, he's got the shipping fever!"
"Shipping fever?"
"It's a virus where you can't stop shipping fictional characters."
"I'm thinkin' Luz and Amity. For Amity, it was confirmed."
"He's been at it for hours."
"That ain't so bad. I ship those two too."
250:1 Royal Hours Later.
"I still say Dipper and Pacifica would make a cute couple."
The Guards can't take anymore. "Please, make it stop!"
"Only fresh air can cure it."
A guard hands him the key. "Here, just get him out of here!"
Donald, Goofy, and the old guy then leave.
"I can still hear it," says Guard-1.
"Now I'm gonna have nightmares about couples," says Guard-2.
...
Donald, Goofy, and the old guy go through the garbage.
"I haven't had to deal with that much garbage since Ma Beegle ran for village leader," says Donald, "come on, we gotta find King Mickey."
"I know where he's at," says the old guy, "follow me!"
...
And so, they followed the old weirdo to the middle of the Dark Forest.
"We have been walking forever," says Donald, "where are we, anyway?"
"The Cave of Amnesia," says the old guy, "King Mickey is in there. Well, I did my part."
"You're leaving," asks Donald.
"After ten years in jail, I've got some livin' to do. Plus, in the forest, I got all the insects I can eat." The old guy leaves.
"Come on," says Donald.
"I wonder why they call it The Cave of Amnesia," says Goofy.
"Probably just to keep out the tourists," Donald enters, "Who am I? Where am I? What am I doing here?"
"You're Donald Duck. You're in the Cave of Amnesia. And you're lookin' for King Mickey."
"Donald Duck, Cave of Amnesia, King Mickey. Got it."
Donald enters again. "Who am I? Where am I? Where is my head?"
"You're Donald Duck. You're in the Cave of Amnesia, looking for Mickey. Your head is on your neck."
"Duck, Cave, King Mickey, on my neck. Got it."
Donald enters the cave. "Who turned the lights off? What am I doing here?"
"YOU'RE IN THE CAVE OF AMNESIA AND YOU'RE LOOKING FOR KING MICKEY!"
"I KNOW, WHY ARE YOU YELLING AT ME?"
"'Cause you went in the cave and kept forgettin'."
"That doesn't sound like me."
"I'll show ya." Goofy enters the cave. "Who am I? Where am I?"
"I see your point. How are we going to find the King if we can't remember who we're looking for?"
"I'll write a note." Starts writing. "We're Donald Duck and Goofy and we're in the cave, trying to find King Mickey." Goofy sticks the note on Donald. "Now, let's go."
...
As Goofy and Donald walk, Donald bumps into Goofy.
"Who are you," asks Goofy.
"Who are you," asks Donald.
"Who are we? What are we doing here?"
"And what's that thing around yer neck," asks Goofy.
"It's a sign," says Donald.
"What's it say," asks Goofy.
"I don't know," says Donald, "I can't read!"
"And I can't read upside down!"
Donald and Goofy freak out until they bump into each other and the note's right side up.
"It says we're Goofy and Donald and we're trying to find King Mickey," says Goofy, "you're Goofy and I must be Donald."
"Wait, I think you're Goofy," says Donald, "because you look goofy."
"If I'm Goofy and you're Donald, then who's this King Mickey character?"
A strange creature shows up.
"Stallem can help you find King Mickeysss."
"Who are you," asks Donald.
"I am Stallem. You must helpy me find the freshness."
"Oh, ya mean fresh air," says Goofy, "we gotta get him out of this here cave."
"Follow us," says Donald.
...
The trio exit the cave.
"Sweet, precious freshness," then the creature became more stable, "wait, I'm not Stallem. I'm King Mickey! Heir to the House of Mouse!"
"Gosh," says Goofy, "it is King Mickey!"
"I guess the cave made us forget what he looked like," says Donald.
"I remember everything," says Mickey, "The Evil King ambushed me and stole my throne. Now we have to storm the castle and take it back! Alright Men, ready charge!"
Mickey, Donald, and Goofy then go into battle.
