To Nicole Peach: Well...it would've been a crime if I didn't give Wheatley and Space Core a cameo. I mean...they're in space for crying out loud!

Bowser (Paper Mario: The Thousand Year Door)

Bowser walked around at Poshley Heights. "So quick question, is there an actual Crystal Star?" He asked.

"I'm pretty positive." Kammy said as they walked around.

"I think the Crystal Star is right in that building." Ansem said, pointing to the Poshley Sanctum.

"Ah." Bowser said as they walked to it...only to see it locked. "Oh for crying out loud." He said.

"Well, we can break in by smashing through a building." Ansem said.

"No way, Ansem." Bowser said as he charged up a punch and punched the lock really hard...which also broke down the doors.

"Wow...that's quite a punch." Ansem said.

"Thanks." Bowser said as they walked straight in the Poshley Sanctum.

"Hey! Look! The Crystal Star!" Kammy exclaimed.

"SCORE!" Bowser yelled as they ran straight to the "Crystal Star".

"I'm surprised Mario didn't get this one." Bowser chuckled.

"That's because he didn't." A voice said as they turned to see Pennington walking up to them.

Pennington (Paper Mario: The Thousand Year Door)

"What are you talking about, you weird penguin?" Bowser asked.

"I'm saying...that Luigi and Roxas have the Crystal Star. This is just a red herring." Pennington said.

"ARE YOU KIDDING ME?!" Bowser yelled. "ARE YOU SERIOUSLY TELLING ME GREEN 'STACHE AND A NOBODY THAT I DON'T EVEN KNOW GOT HERE FIRST?!" He continued to yell.

"I wasn't aware Roxas was with Sora." Ansem said.

"These Mario Brothers...i'm going to KILL THEM once I find them! And take out this Sora dude too...along with Rox-what's-his-face." Bowser said angrily.

"Lord Bowser! Sir!" A voice exclaimed as they turned to see a Paragoomba flying in.

"Paragoomba? What's going on?" Kammy exclaimed.

"Mario and Sora have all the Crystal Stars and are going to the Thousand Year Door as we speak!" He said.

"Not on MY watch they don't!" Bowser exclaimed. "Let's go. To the really old door!" He ordered as they all walked off.

"...I don't know what just happened." Pennington said.

Meanwhile...

X-Naut Fortress (Paper Mario: The Thousand Year Door)

Everyone walked out of the room as Sora held on to the Crystal Star.

"Sooo, how do we get out of here?" Koops asked.

"I have no idea." Sora said, as they walked around.

"Wait a minute" Lightning said, getting their attention. "Remember that door at the bottom floor after we discovered Peach and Kairi aren't here?"

"You mean the one we couldn't open?" Sora asked.

"Yeah." Lightning said. "I just have this feeling it's open now." She said.

"Hmm, let's find out." Mario said as they walked to an elevator and walked in, as it went down to the bottom floor.

They walked out and looked to the right. "That the door you mentioned?" Yoshi asked.

"Yep." Lightning replied as they walked to the door, as it automatically opened.

"Well...let's go in." Sora said as they walked in, to see a certain computer.

"You're...Sora and Mario and friends...are you not?" A voice asked.

"Whoa, what was that?" Mario asked.

"I'm...here...the computer...I am...TEC." TEC told them.

Xion (Kingdom Hearts 358/2 Days)

"So you're TEC that Peach and Kairi told us about? What happened?" Sora asked.

"Grodus...shut me down before...they could make their...escape...but...I had a backup...but even it's failing on me..." TEC said.

"Where's Peach and Kairi if they're not here?" Mario asked.

"Mario...they're at...The Thousand Year Door..." TEC said, and then suddenly his screen started to get a little fuzzy. "Agh...it's almost..." He said but couldn't say it.

"They're inside the door? How did they get inside?" Vivian asked.

"Xemnas...used a portal...so they could easily go through the door..." TEC explained. "Before I forget...it was not an internet connection failure that caused the email to...cut off...it was Grodus who did it..." He said.

"Oh, that answers that question." Yoshi said.

"Please...you must...go to the door and save the both of them...before it's too late." TEC said. "It's too late...for me to go on..." He said as his screen started going fuzzy big time.

"We will." Sora said.

"Before...you go...tell...Peach and Kairi...that...I appreciate for all that they did...for me..." He weakly said as suddenly the whole room went red.

"Wait...what are you...?" Koops asked.

"I...am taking this place with me...I activated the self-destruction...hurry...you must get to...the door." TEC said.

"But we don't know how to get out of here." Sora said.

"There's...a teleporter room...on the second floor...i'll make the red light green...so you can go in and save the girls..." He said...and then he shut off.

"We understand TEC..." Goombella said. "We need to get out of here...now." She said as they nodded and ran off.

As soon as they got to the second floor, they noticed a door with a green light as they all ran to it and walked in.

"There's the teleporter." Vivian said as Mario ran to it and pushed it.

"Go go go!" Mario ordered as they all ran in the teleporter, teleporting back to Rogueport.

"Peach...Kairi...goodbye..." TEC weakly said as the whole place blew up.

Rogueport Sewers (Paper Mario: The Thousand Year Door)

"Did you guys hear something?" Sora asked as they got out of the teleporter.

"I heard TEC's voice one last time. He probably said goodbye before he took the whole place with him." Vivian said.

Mario put his hat over his chest, thinking about TEC before putting it back on. "Let's-a go." He said as they walked out of the door.

"Well if it isn't you guys!" A voice exclaimed as they turned to Frankly.

"Oh hey Professor." Goombella said.

"I imagine you got the last Crystal Star?" He asked.

"Yeah." Sora said.

"Alright, quickly...to the Thousand Year Door." He said as they all ran off to the door.

The Thousand Year Door (Paper Mario: The Thousand Year Door)

"Here we are." Frankly said as Mario walked up to the pedestal and got on it.

The whole place glowed as every Crystal Star appeared, and then suddenly the whole place rumbled, as the Thousand Year Door opened up.

"Oh! This is so exciting!" Frankly exclaimed. "Now go on in and defeat the demon!"

"Right." Sora said as he looked at them. "Let's go in and save Peach and Kairi...for TEC."

"Right." Mario said as they all walked in the Thousand Year Door.

I decided to combine the final Bowser scene with the other scene. It was short so I thought i'd combine it with the other.
