Bowser's Castle was burning as usual, with Mario and Sonic The Hedgehog zipping through the castle in an attempt to see who was better at navigating the fiery homestead of Bowser. However, as Sonic went through a giant gray warp pipe, Mario stopped in his tracks, a giant blue square shaped Thwomp landing in front of it.

"URGH!" The Thwomp exclaimed as he glared at Mario.

"Mamma mia!" Mario exclaimed as he backed away, raising his hands in shock as he shook his head, blinking.

It was then that Bowser appeared in his Koopa Klown Kar, laughing at Mario as he pointed at the red capped plumber. "Bwahaha! Stumped, Mario? I have been placing these old 64 styled Thwomps back into my castle!"

Mario rolled his eyes as he folded his arms together, sighing. "Yes... I noticed..."

All of a sudden, making for a surprise return, Sonic kicked his way right through the Thwomp, breaking it in peaces as the blue hedgehog landed on his feet, standing up. Mario and Bowser gasped as they noticed that Sonic was taller, and had a brown scarf around his neck.

"What?" Sonic asked as he rolled his right hand around, his voice slightly deeper pitched.

Mario shook his head as he opened his arms out. "Sonic... what happened to you in there?"

Sonic glanced up at the shocked Bowser, chuckling as he turned to Mario, wrapping his blue, lanky arms around the back of his head. "Oh. I just had a Sonic Boom, that's all."

Bowser blinked as he shook his head, piloting his Koopa Klown Kar to the northern direction. "That's it, I'm out of here."
