Back at the lab, Donnie was panicking about accidentally sending Mike to the past.
"What have I done, what have I done, what have I done? I did something stupid. I just sent Mike back to the past. Got to get him back before he creates a time paradox and puts a hole in the space-time continum." said Donnie.
Zoey walked in the basement.
"Hey Donnie." said Zoey.
Donnie screamed in fear, turned around and saw Zoey.
"Oh, I thought it was Splinter." said Donnie.
"Have you seen Mike?" asked Zoey.
"Oh him? Yeah, he's…uh…at a…uh…space heroes…uh…convention with Leo." Donnie lied.
Zoey wasn't buying it.
"You sent him to the middle ages, didn't you?" said Zoey.
Donnie decided to come clean.
"Yes I did." Said Donnie.
Zoey then proceeded to beat up Donnie as he screamed. Seconds later, Zoey finished beating Donnie up and was still angry.
"How could you send him through time?" said Zoey.
"I thought it was a dimensional portal." Said Donnie.
Zoey sighed knowing that Donnie has a point.
"Look maybe Raven and Karai can help." Zoey said.
"I'm trusting Raven, but not Karai." Said Donnie.
"Why not Karai?" said Zoey.
"No one else in the mansion trusts her, she's the daughter of Shredder, and is working with a crime boss." Said Donnie.
"Give her a chance." Said Zoey.
"Give her a chance? She obviously has something planned with your boyfriend. Try to imagine what's happening to him at this minute." Said Donnie.
Zoey is mad.
"Hey Karai is my friend and your adopted brother's best female friend from kindergarden." Zoey said. "Just try and trust her and give her a chance and you will see."
Donnie sighed.
"Fine I will trust her for you and GDN's sake." Donnie said. "Though she is at a Halloween Party with him and Debbie."
Meanwhile in the Middle Ages Mike woke up and he looked around and he saw he was in bed.
"What the?" Mike said. "Where am I and how did I get in this bed?"
"You're in our kingdom" said a voice.
Mike turned and saw what looked like Randy Cunningham and Theresa Fowler dressed in royalty.
"Randy? Theresa, what are you two doing here?" Mike asked.
The two looked confused.
"Who are they?" The princess asked.
"No idea sis but father wants to see him." The prince said and looks at Mike. "Come stranger our parents want to see ya."
With that they took Mike to the Main chambers.
Mike became surprised after seeing that the king and queen also looked like Randy and Theresa.
"Randy, Theresa?" said Mike.
"Who are those guys? I'm King Ronald." said the king.
"And I'm his queen, Queen Tiffany." said the queen.
Mike put two and two together.
"Great, that dimensional portal turned out to be a time machine. By the time I get back, I'm going to kill Donnie." said Mike.
"Never mind that, what matters is what you're doing here." Said Queen Tiffany.
"I have no idea what I'm doing here. All I know is that I stepped into a portal and ended up here." Said Mike.
The king and queen then became surprised.
"Then you must be the chosen one." Said King Ronald.
Mike became confused.
"What?" said Mike.
"You're the one that is destined to save our kingdom." Said the prince.
"Oh, where are my manners. Sir…" said King Ronald.
"Where I come from, my friends call me Mike." Said Mike.
"Sir Mike, these are our kids, Prince Romeo and Princess Trini." Said King Ronald.
Mike bowed down to the prince and princess.
"I shall be in your service." Said Mike.
"You're here because our kingdom is in terrible danger." Said Queen Tiffany.
"What's your kingdom called?" said Mike.
"Toon-a-Lot." Said King Ronald.
Mike then remembered something.
"Toon-a-Lot. This is the 'future' place of Toon City." Said Mike, "Who's terrorizing your kingdom?"
"A fire breathing dragon." Said Princess Trini.
Mike then became surprised.
"Wait, I have to kill a dragon? I know a dragon, and he's mostly human." Said Mike.
"Still, you need to slay the dragon so that our kingdom will be saved." Said King Ronald.
"How can you be certain that I'm the chosen one?" said Mike.
"Because he'll be able to pull a sword out of the stone in our court yard. We need to see it." Said Queen Tiffany.
The five left the main chambers.
"Could this day get any more weirder?" Mike said to himself.
Back in the present, Shaggy parked his van close to where the medieval fair was at.
"Like, here we are man." Said Shaggy.
"Nice, how does Scooby feel about it?" said Danny.
Scooby poked his head up from behind the seat.
"Very rood." Said Scooby.
Shaggy looked at Scooby with a confused look on his face.
"How'd you get out of that wooden horse?" asked Shaggy.
Scooby pulled out a blow torch.
"Brow rorch." Said Scooby.
"Like, that's a smart dog." Said Shaggy.
"That coming from some guy that eats dog food all the time." Said Danny.
Shaggy was eating some Scooby Snax and hid them behind his back after hearing what Danny said.
"Rets enjoy ra rair." Said Scooby.
"Lets." Said Danny.
