A/N. New chapter. Not much else to say except enjoy. Also I don't own Regular Show or Mario.

Mordecai and Rigby were now walking down the path to Acorn Plains Way. Finally after a few minutes, they made it.

"Alright, we made it to Acorn Plains Way. Let's go." Rigby said, before getting pulled back by Mordecai.

"Wait dude, look over there." Mordecai said, pointing at none other than the infamous Goomba.

"It's those mushroom things. What do we do?" Rigby asked.

"Don't you remember? In the game, you jump on them." Mordecai answered.

"OK, I'll get rid of him." Rigby said before running to the goomba.

"What the? That's not Mario or Luigi." The goomba said, before getting jumped on. "Now I'm flat as a pancake. How nice."

Mordecai and Rigby then ran underneath some blocks.

"Hey those are blocks from the game. Let's see what comes out of them." Mordecai said, hitting the block with his head causing two of the acorn like mushrooms to roll out.

"Hey, aren't these mushrooms the ones that change you into a squirrel from the game?" Rigby asked, holding one of the mushrooms.

"Yeah I think they are. But I think in order to change into a squirrel suit, we got to eat these things." Mordecai answered

"If you think I'm going to eat this thing then you're crazy." Rigby replied.

"JUST EAT IT!" Mordecai shouted at Rigby.

"Fine." Rigby said in disgust, before shoving the mushroom down his throat. "You know, that tasted like pizza. I could eat one of those again." Rigby said, suddenly having a squirrel suit form on his body. The same happened to Mordecai when he ate his mushroom.

"This is amazing, let's go continue." Mordecai said, before running off. At that moment, he stopped above a pit.

"Dude, how deep do you think this is?" Rigby asked, perplexed at the depth of the pit.

"I don't know, let's just avoid it." Mordecai replied. The two then jumped above the pit and to the other side. Above them, a Waddlewing flew over, found the two and dive bombed at them.

"WATCH OUT!" Mordecai shouted, grabbing his pole and whacking the Waddlewing with it. The Waddlewing fell out of the air and into the pit. The two then noticed a huge coin spinning in the air. Of course, Mordecai and Rigby were persuaded by the coin's possible wealth and flew to collect it.

"Man, Benson will be so happy and give us a weekend off when we give this coin to him." Mordecai said, stuffing the coin inside his suit's pocket.

The blue jay and raccoon continued onwards and found a room with blocks outside, but strangely, it was floating.

"What's in there?" Rigby asked. "I'm going to find out!" Rigby exclaimed, hitting the blocks causing them to break. He was met with the sight of a lot of gold coins.

"Dude, do you still have your wallet?" Mordecai asked, recently climbing into the room.

"Yes I do." Rigby answered, grabbing the coins and putting them into a wallet. Mordecai and Rigby then jumped out of the room and onto a hill that was moving up and down. The duo then jumped onto the next hill and came across a flag of Bowser's face.

"Man, this face of Bowser is ugly. I bet the artist who designed it went blind." Rigby said, before he and Mordecai laughed.

"Yeah dude, let's make it better." Mordecai said, changing the flag into a flag of himself and Rigby. Mordecai and Rigby then slid down a hill running into two goombas and made the goombas get sent flying away, knocked out. They encountered a green pipe, a Piranha plant came out, chomping the air like usual. The two ignored it and came across two pipes, one colored like gold and another one green.

Mordecai and Rigby came across another hill and went down some steps. There was another Waddlewing but Rigby managed to defeat it using his frying pan and also a Goomba. Mordecai and Rigby then flew up onto some floating stairs with their squirrel suits and saw a Green pipe.

"Hey Rigby, what do you think is up there?" Mordecai asked.

"I don't know. Let's go find out." Rigby replied. The two climbed up the pipe and were inside this rainbow block like place. In the air below, there were a lot of Waddlewings flying around. The blue jay and raccoon then jumped and landed on heads of Waddlewings sending the squirrel enemies falling to their dooms. Finally, at the bottom, there was another Star Coin. The duo then collected the Star Coin, landed on the ground, and went into the pipe and went back to the ground.

Soon Mordecai and Rigby made it to some wooden steps, climbed up, and there was the flag pole. Mordecai and Rigby then jumped to the flag pole and made it. They pulled their flag all the way to the top and ran into the brick castle.

"Man, if Margaret could see me now, fighting monsters and saving a princess." Mordecai said, resting on a chair inside the brick castle.

"Alright so according to a sign the next place we go is called...Tilted Tunnel." Rigby said, reading a sign.

"Alright, we rest for a few minutes then head off to Tilted Tunnel." Mordecai said.

Now as for the Mario bros, they were stuck doing Mordecai and Rigby's chores.

"Alright Luigi, the first chore on the list is rake leaves." Mario said, reading the list of chores.

"Alright bro, we need some rakes. But couldn't we at least get a job to unclog some toilets? I mean we are plumbers after all." Luigi complained.

"Luigi, don't complain. We just do these chores for that gumball machine and he's happy." Mario said.

"Alright fine, But I won't enjoy this." Luigi complained.

The brothers soon got their rakes and went to the middle of the park field where there were a lot of leaves, also none other than Muscle Man, who was just diving into leaf piles.

"is that a zombie?" Mario asked, pointing at Muscle Man.

"Well he doesn't look like he's decomposing or rotten." Luigi said.

The two brothers went to approach Muscle Man and introduced themselves.

"Hi there, my name is Mario and this is my brother Luigi." Mario introduced.

Muscle Man just stared at the two plumbers, then cleared his throat. "You know who else's name is Mario and Luigi? MY MOM!" He shouted.

"Your mom's name is Mario and Luigi?" Luigi asked, perplexed.

"It's supposed to be a joke. My name's Muscle Man, AKA the park's muscle. I originally left a gift in that leaf pile for Mordecai and Rigby but you can have it. Just jump inside." Muscle Man said.

"Well that was real nice of you Muscle Man." Mario said, sitting in the leaf pile, only to hear a noise that sounded like a fart, then looked in the leaf pile to see a Whoopee Cushion. Muscle Man started cracking up at this.

"HAHAHAHA YOU TOTALLY FELL FOR IT! BOY, YOU SURE ARE EASY TO PRANK!" Muscle man shouted, crying and laughing at the same time.

Mario was not amused. "It's going to be a long day." He muttered under his breath. Mario and Luigi then left the scene leaving Muscle Man to continue his laughing and crying.

A/N. Chapter 3 is done. Hope you enjoyed it. Next chapter will be about Mordecai and Rigby going through the next level while Mario and Luigi will fall for more of Muscle Man's pranks. Anyways, please leave a review. I'd really appreciate it.
