Norfair

Snake was searching for a new box. After Ridley ate the old one, Snake was determined to replace it. And nothing would get in his way.
"HEY SNAKE!" Snake turned around. Nobody was there.
"Strange." Snake said to himself.
"SNAAAAKKKKEEEE!" the voice persisted.
"Who's there?"
"IT'S SHULK TIIIIIMMMMMEEEE! OH YEAH!" Shulk jumped off Charizard, who was flying around the fiery stage. Then, the Monado boy (still in his underwear) ran around the stage, only to be thrown off by Snake himself.
"Shulk Time's over now, Shulk."
"Yay!" Charizard leapt for joy.

Then he got thrown into the lava by Ridley, who sang a song.
"I came in like a wrecking ball!" yes, he did just sing Miley Cyrus's 'Wrecking Ball'.
"RIDLEY! GIVE ME MY BOX BACK!"
"But Snakey! I ate it!"
"I WANT MY BOX BACK!" Snake started to throw grenades at Ridley and shoot him with his gun. "YOU WILL PAY FOR EATING MY BOX!"
"Calm down Snake. It's just a box." Falco scoffed from inside his Arwing.
"NOOOO! I NEED MY BOX! OR ANY BOX! AS LONG AS IT'S CARDBOARD!"
"I ATE IT! Do you want to ride on me instead?"
"Okay!" Snake jumped onto the giant boss and off they flew.

"Hey! What about me?" Charizard complained.

Smash Mansion

Sóllilja, Sonic, Sanic, Lunette and Rin were interrogating Samus, asking the bounty hunter about Ridley.
"Where would Ridley go?" Sóllilja asked.
"Right now, he would probably go to Norfair, or the Pyrosphere, or maybe the Halberd. I don't know for certain."
"How fast is he?" Sonic asked.
"Faster than Lunette, that's for sure!"
"Hey!" Lunette complained. "I'm a gunner! I don't have to be fast!"
"Oh yeah? You is da second slowest smasher in dis place!" Sanic said.
"Look who's talking!" Sonic started.
"I iz faster den you, Sonic da Hedgehog!" Sanic argued.
"I'm the fastest smasher here!" Sonic shot back. Rin looked at him. "Oh. And Rin's the fastest too." Rin smiled.
"ENOUGH!" Sóllilja yelled. "Samus, what mood is Ridley in?"
"A crazy one."
"Damn. Crazy ones are hard to catch."

"He's a magical Ridley flying through the sky!" Snake sang as he crashed through the mansion whilst riding on Ridley.
"On a magical journey to the other side!" Ridley joined in.
"Shoot him down." Falco said. Samus loaded her gun - and shot Ridley down.
"OH NO!" Ridley cried.
"NOW I CAN'T FLY ON THE MAGICAL RIDLEY ANYMORE!" Snake moaned.
"Yay!" everyone else said.
Chrom and Male Robin walked past. They shook their heads at Ridley and Snake.
"Gay." they both said before walking away.
"Oh well," Rin said "at least we saved Falco."
"I did." Samus interjected. "And my work's done."
Samus walked away.

"I'm glad that's over." Sóllilja smiled. For once.
"And no thank you for saving me, Sól." Falco made her jump. Sóllilja scowled and gave him a fiery exploding side kick and destroyed a wall. Captain Falcon was there.
"Come on! Show me your moves! Faaaaaaaaaallllllccccoooooooooonnnnn Puuuuuuuuuuuunnnnnncccccchhhhh!"
"OH NO YOU DON'T!" Yoshi yelled. The green dinosaur threw a bottle of Jack Daniels at the F-Zero racer.
