This story takes place in 2011 :)

"That's a so nice!" Mario said while sliding down a flagpole. For some strange reason, he walked into a castle with luigi and yoshi. They ended up in another castle which was next to a green pipe. "I'm tired of going in the bottom pipe. Let's go in the top one this time!" said Mario. They went into the pipe. They came out another pipe in a strange place that they had never seen before. "Bwa ha ha ha!" laughed Bowser and Wart. "Now that you found your way into world 9..." said Bowser, "You'll have to find your way out!" Wart said. He then laughed in unison with Bowser. Luigi said, "Mama mia Mario, how will we get out of this mess?" "I don't know, Luigi, but what I DO know is that Yoshi can help us", said Mario.

There were koopalings on the other side of all 8 pipes (Bowser jr. Included) and the Mario bros almost admitted defeat, but they thought of a plan. They had been to the minus world before, and they found a warp zone that took them back to the mushroom kingdom. At the time, the minus world was exactly the same as world 9, but underwater. Mario figured out that there should be a warp zone somewhere, so they started looking around.

The first obstacle was a bottomless pit. Mario was riding on yoshi, so yoshi helped him jump over the hole by flutter jumping. Luigi can flutter jump as well, so he went over on his own. There was the warp zone, behind the (extremely safe) axe. Mario, yoshi and luigi had to go through 4 more obstacles to get there, and they were never gonna give up. The next obstacle, obstacle 2, was a set of 10 thwomps with lava underneath. Yoshi can walk on lava, so he went under, making the thwomps go down. Mario & Luigi had to spin jump on the thwomps so they could get across.

The third obstacle was Bowser jr, and they had to fight him. Jump on his head 3 times, ground pound on his head 2 times or jump on his head 1 time then ground pound on his head 1 time. I'm gonna let you decide what they do. Anyway, Mario, Luigi and Yoshi beat him. Bowser jr joined them and showed them where to go next. "Mama mia! I must be dreaming!" Mario said in disbelief. "I've never seen so many powerups!" "take whatever you need, it's all yours!" Bowser jr said. Yoshi got a pair of wings, Mario got a cape and Luigi got a Tanooki Suit. However, they had a bob-omb in them which would explode if Mario, Luigi and Yoshi didn't make it in an hour. The pressure was on them. They had an hour left. The bob-ombs had already attached. They were a goner.

They saw a flash of blue. Then another. Then another. And yet another. Mario fainted. He thought he woke up, but he was still knocked out. He dreamt about marrying peach. Bowser thrashed the wedding, ate the cake and kidnapped peach. Mario woke up. He saw Sonic. Sonic said, "Hey, man. I wouldn't let the king of video games die. Let's go." So off they went, travelling faster than the speed of sound. Mario wanted revenge on Bowser. Bowser ate his cake. Mario wanted to try some cake. Whenever Mario rescued the Princess, the cake was always a LIE! Sonic found a way to get past all the other obstacles in less than an hour, so they started moving. After a while, Mario, Sonic, Luigi and Yoshi saw nothing but white.

The bob-ombs fell off. Everyone was transported to peach's castle. "Sorry for being late Mario, but happy 25th anniversary!" said peach while holding up a cake. Mario took a piece. He liked it. Sonic was confused. "Wait, wasn't it his 25th LAST year?" Sonic said. Peach said, "It was, but I was too busy being kidnapped! That doesn't really remind me, but I remembered something!" Peach went into the kitchen and brought out two cakes. One was for Sonic's 20th anniversary, and one was for Luigi's 25th. "Happy anniversary, everyone!"
