Here's the final chapter. Sorry if it sucks, because I'm not good at writing fight scenes.

Mario and Luigi ran through the door which led to the school yard - and stopped in their tracks.

They could see that on the other side of the school yard, Peach was sitting on the branch of a tall tree. Bowser had somehow managed to climb the tree while carrying the Princess, placed her on the branch and climbed back down. Peach decided not to jump down, for she saw it as a chance to be rescued by Mario, which she had always wanted since she had met him. Any doubts she had when Bowser had placed her up the tree had now vanished when she had seen Mario dash into the school yard to rescue her.

The rest of the children in the school yard were looking up at Peach in horror, hoping someone would save her. None of them dared to approach the tree, for Bowser was leaning back against the trunk, his arms crossed, a sinister smile on his face. The children could tell that despite being young, Bowser was very villainous and not to be crossed.

Mario, however, was confident he could save Peach, as he believed with his moustache, he could do anything. He took a few steps forward. "Get my Princess down from the tree, Bowser!"

Bowser turned to Mario and sneered. "You'll have to come and get her!"

"Fine," sulked Mario, "I'll come get her."

Peach's eyes widened and she smiled happily. She was finally going to be rescued by her hero with a moustache.

"I'll come help you," said Luigi to Mario.

"No way, Luigi! This is my job! I'm the hero!"

"You told me you wanted to be a plumber."

"I do - but I wanna be a hero too!"

"So do I!"

"You're no hero, Luigi. If you came up there with me, you would just knock Peach out of the tree - or make it fall onto its side."

"Mario!" Peach called impatiently from the tree, placing her hands on her hips and looking down at her hero with an annoyed expression. "Are you gonna come save me or what?! It's not polite to leave a Princess waiting when she needs to be saved!"

"Okay, okay. I'm just dealing with this loser. I'm coming now, Peach."

Bowser stepped away from the tree and stood to one side, keeping his arms crossed. Mario walked towards the tree, not taking any notice of his brother's hurt expression. As Mario approached the tree, he grinned up at Peach. She grinned back - then suddenly looked horrified. "Mario! Move!"

Mario stopped in his tracks, looking up at Peach with puzzlement - then cried out in pain as Bowser kicked him in the side, sending him rolling on the ground.

"MARIO!!!" the watching children cried in unison. Luigi watched his brother roll on the ground. He had never realized how weak his brother was.

Mario stopped rolling and quickly jumped to his feet. Rubbing his side, he glared at Bowser. He would not let the Koopa get away with kicking him. Mario charged at Bowser, his right hand clenched into a fist - and fell backwards with a cry of pain as Bowser punched him in the face. The children all watched, looking horrified, as Mario landed on his back and lay where he was.

Luigi looked up from his brother to the Koopa, who was smiling evilly down at Mario. Bowser then looked up at the children and his sneer widened. He wanted them all to be afraid of him.

Luigi was now angry. He would not let the bully that stood before him get away with what he was doing. Luigi took a run towards Bowser, trying to hit him - only to get kicked in the stomach by the Koopa. The children watched in surprise as Luigi stepped backwards, moaning in pain, clutching his stomach. Up in the tree, Peach was getting impatient. She had been hoping to have been rescued by then.

Luigi looked up at Bowser, feeling even more angry. Before he could attempt to attack again, Bowser swung hus fist around and struck the boy in green on the left side his head. Luigi cried out in pain and fell onto his right side near where his brother lay.

"You won't defeat me!" Bowser boomed out loudly, trying to sound as evil as possible. "No one can defeat Bowser!"

Luigi remained lying on the ground, gasping in pain, his eyes filled with tears. He was sure he was unable to defeat Bowser and save the Princess. He was too weak.

That was when Luigi noticed a strange Mushroom embedded in the ground within his reach. It was yellow with large red spots. Luigi remembered the teacher explaining to the class that there was something special about this type of Mushroom, but he couldn't remember what it was.

"Are you ready to die?"

Upon hearing Bowser's words and hearing him come running towards where he lay, Luigi quickly reached out, grabbed the Mushroom, pulled it out of the ground, jumped to his feet to face Bowser and quickly took a bite out of the before swallowing.

Bowser stopped in his tracks and, along with Mario, Peach and the rest of the children, watched with shock as the Mushroom took effect on Luigi.

The small boy started to grow into a giant. He grew taller and taller, passing the height of the tree, then the height of the school. Soon, Luigi was looking down at Bowser and the children, who he could barely see, as they looked very tiny to him.

Bowser remained looking up at the giant boy in green in shock for a few seconds, then ran quickly over to his giant left shoe and started to kick it. "You're still weak. You may be a giant, but that doesn't make you stronger. I'm the strongest. You can't defeat-"

At that moment, Luigi raised his giant left foot back. Bowser's eyes widened, for he instantly knew what Luigi was going to do to him. However, instead of running away, he raised his hands up and started to protest. "No! No! No!"

Luigi raised his giant left foot as high as he could, then kicked out.

"NOOOO!!!"

Luigi's foot struck Bowser hard, sending him to fly high into the air and soar quickly away from the school, soon to disappear out of sight and land fifty miles away in a bog.

"Luigi!" Peach called up to him, trying to be heard. "You beat him!"

Luigi heard the young Princess and smiled. "Yeah! I beat him!"

"Well, aren't you going to get me down?!"

"Huh?! Oh, sure!" Luigi bent down and took hold of the trunk of the tree, surprising Peach in the process. Before she could ask what he was doing, Luigi pulled the tree out of the ground with all his new strength, causing Peach to fall off the branch she was on with a scream and land on her back onto the ground. She winced in pain and glared up at Luigi, who looked down at her apologetically and dropped the tree (which just missed Mario), before shrinking back to his normal size.

As Peach picked herself up, the headmaster came running out of the school. He was a middle-aged man, with short brown hair and a brown moustache (which nobody thought was as cool as Mario's). He was dressed in a pale blue buttoned shirt with black jeans and shoes. He stopped where the crowd was gathered. "What's going on out here?"

"Mario defeated Bowser," replied one of the children, pointing at Mario, who was just picking himself up off the ground. He had quickly recovered from Bowser's assaulted, but had decided to laze on the ground and let his brother take on the Koopa.

"What do you mean?" the headmaster asked suspiciously. Neither he or anyone else noticed the shocked expression on Luigi's face. The young boy in green couldn't believe that the children had seen him defeat Bowser, but still chose to praise Mario over him.

"Mario turned into a giant and kicked Bowser out of the school," the child explained with a smile.

The headmaster turned to Mario, who was now up on his feet. Hearing what the child had said, Mario nodded with a grin. "Yes, Sir! I'm surprised you didn't notice me, since I was so tall! You should have seen me kick Bowser! He went flying!"

The headmaster stared at Mario in silence. Luigi was about to speak up to say how he had been the one to defeat Bowser, but knowing that the headmaster liked Mario as well, he knew it was worthless. He sighed glumly and decided to wait to find out what the headmaster would say to Mario instead of him.

The headmaster walked up to Mario and looked down at him sternly. "Well then, Mario. For what you did, you are - expelled!"

"WHAT?!" all of the crowd of children cried in unison and horror. Luigi had cried it with them, unable to believe what the headmaster had told Mario.

"You all heard me." The headmaster looked around at the crowd of children. "Mario is expelled."

"But it wasn't me!" Mario suddenly cried out in panic. "It was-"

"Don't try and lie, Mario. Everybody here knows it was you."

"It wasn't, Sir," protested Peach. "It was-"

"Shut up!" The headmaster raised a hand up to Peach without looking away from Mario. "Get away from my school, you bully."

"But-"

"GO!!!" the headmaster roared before turning away and heading back into the school.

Mario quickly turned to Luigi and pointed at the headmaster. "Luigi! Tell him it was you!"

Luigi grinned. "No way, Mario. This should have happened to you a long time ago. You are a bully, but thankfully, I don't have to put up with you here anymore." Luigi then turned, still grinning, and headed into the school building.

The children watched Luigi leave with shocked expression, then they all turned sadly to Mario, all upset that he had been expelled.

Mario sighed unhappily. "Mamma Mia."

There we go, everyone. I sure hope you've enjoyed my first Mario story and it's managed to give you a few laughs. Thanks for taking the time to read. :)

Cheerio.
