Two parents were getting ready to leave there home

Mom: Now where is that babysitter?

Dad: Well you don't think Billy's bad reputation could've scared him away?

Mom: Now don't be silly! Billy is a wonderful child!

Billy dropped a vase but made it look like the cat did it

Mom: Oh Kitty how could you?

Then Mario Luigi and Daisy fell out of a warp pipe and landed in the kitchen

Daisy: Ow! I think we took the wrong pipe

Luigi: then where are we now?

Mario: Only one way to find out!

The three of them looked out the window and saw Brooklyn

Luigi: I don't think we're in the Mushroom Kingdom anymore!

Billy walks to the entrance of the kitchen and sees them

Mario: You're right because if that's not the Brooklyn Bridge my name's not-

Just then the mom walks in the kitchen

Mom: Oh there you are! You must be the babysitters! I guess Billy let you in the side door and I am so glad there are three of you because Billy  is quite a handful!

She gave Mario a list of phone numbers

Mom: Here's the phone number of our doctor this one's for the theatre!

Daisy: you have the wrong-

Mom: Snacks are in the fridge help yourself to lasagna!

Mario: Lasagna?!

Luigi: But we're not-

Mario: shh! That lasagna looks good!

Daisy: what happened to going on a diet?

Mario: I can take a break from that for one day

The mom took Mario Luigi and Daisy to the living room

Mom: We'll be back by 10:30 and could you please give Billy a bath? Have a nice evening I know we will!

The parents ran out of the house and drove off in there car

Mario: Uhh... plumbers log number 40 turns out we're taking care of Billy for the day

Luigi: I guess we're babysitters!

Daisy: it can't be that hard right? Remember when you guys took care of me when I turned into a baby?

Luigi: yeah but that wasn't easy at all!

Mario: calm down bro! What should we do first?

Billy: Hide and seek! Let's play hide and seek! And you dummies are it!

Billy ran off to hide somewhere

Daisy: that kid reminds me a lot about junior...

Mario: come on this could be fun!

Mario Luigi and Daisy closed there eyes and started counting to 100. Then Billy found the warp pipe they came out off

Billy: Oh boy! They'll never think of looking for me in here!

He went into the warp pipe and traveled to the mushroom kingdom

Mario Luigi and Daisy: 99... 100! Ready or not here we come!

Billy arrived in the mushroom kingdom

Billy: Wow! This place is awesome!

Suddenly koopas threw there boomerangs at Billy but he grabbed one

Billy: Alright!

He throws the boomerang back at the koopas but it hits a tree and it falls on top of them

Billy: This is the life! I hope Mario Luigi and daisy never find me!

Ludwig Roy and Larry just happened to be walking nearby

Ludwig: Oh look! That strange little fella! He's a Real Worlder!

Billy: Hey mondo bizarro dudes! Who are you and where am I?

Larry: You're in the Mushroom Kingdom kid! I'm Larry Koopa! the youngest of the koopalings

Roy: I'm Roy Koopa! The meanest of the koopalings

Ludwig: I'm Ludwig von koopa! The oldest of the koopalings

Larry: And any enemy of the Mario Bros and Daisy is a friend of ours!

Billy: Say just in case those idiots follow me here could you guys help me have some fun with them?

Larry: Kid this could be the start of a beautiful friendship!

The four of them hid in the bushes and saw Mario Luigi and Daisy come out of the pipe

Luigi: Well if Billy's here he could be in big trouble!

Daisy: I bet he tricked us so he could run away!

Mario: we don't know that! Maybe Billy just got lost

The three of them could hear billy calling for help

Luigi: billy where are you?

Suddenly two Ptooie piranha plants started shoot spike balls at them

Mario: Oh no Ptooies! And they're spitting mad!

Daisy held her baseball bat

Daisy: I got this! Batter up you stupid plants!

She hit the spiked balls back at the Ptooies and theh run off

Daisy: yeah you better run! Uh... what were we doing again?

Mario: looking for Billy

Daisy: Oh right!

Ludwig Roy Larry and Billy arrived near a cave

Ludwig: Now if you can lure the Mario Brothers and Daisy up here we'll play a trick they'll never forget!

Larry: time for some acting!

Mario Luigi and Daisy saw Roy pick up billy

Mario: Look there's Billy!

Daisy: Roy's got him!

Billy: Help me!

Luigi: Well let's go!

They run after Roy who runs into the cave. Then Roy puts down Billy when he gets inside

Billy: This is great! I can hardly wait to see the look on their faces!

Mario Luigi and Daisy ran into the cave

Daisy: let him go Koopalings!

Mario: We're here to save you Billy!

Billy: I don't want saving! Bye bye babysitters!

Just then rocks fell from the ceiling blocking they're path allowing Billy to run off again

Mario: Hey what's going on here?

Daisy: Billy made friends with the koopalings!

Luigi: we're in big trouble now!

Daisy: we just have to get out and find another way in!

Ludwig rolls a boulder in front of the cave entrance from the outside

Ludwig: no on my watch! We just caught ourself a pair of babysitting plumbers

Billy: That was so cool!

Ludwig: Yeah! But the best is yet to come!

Larry started turning a wheel on a pipes

Billy: Hey guys this is just for fun isn't it?

Ludwig: Oh course it is and I'm having a great time!

Billy: Ludwig what are you doing anyway?

Ludwig: Filling the cave up with lava silly! What does it look like?

Larry: Look kid! You've been real helpful! But the truth is Billy we really don't like you very much!

Roy: Which is why we're getting rid of you!

Ludwig: Right now!

Roy threw Billy into a warp pipe. Then cave Mario Luigi and Daisy were in started to fill with lava

Luigi: Looks like it's a hot time in the old volcano tonight!

Mario: And If we don't get out of here fast we're toast!

Daisy held her baseball bat again

Daisy: I have an idea! you might want to stand back!

She broke a block in the wall giving the three of them a way out

Daisy: after you Luigi!

Luigi crawls through the hole but gets stuck

Luigi: I-I'm stuck!

Mario: Not anymore!

Mario pushed Luigi out and Daisy followed them

Luigi: Whew that was a close one!

Daisy: not yet!

She grabbed the block and put in back in the wall

Daisy: ok now we're safe

Mario: great quick thinking daisy!

Daisy: thanks! It's what I do best

The three of them could hear the Koopalings and started to eavesdrop

Larry: Haha! Did you see the look on that brat's face when we threw him into the Pipe Maze?

Luigi: Oh no! Billy could be lost there forever!

Daisy: he could end up anywhere in the pipe world!

Mario: I'd hate to have to tell that to his mom!

___________________________________

Mario Luigi and Daisy used a pipe to get to the underground

Luigi: Daisy are you sure Billy is down here?

Daisy: yeah this cave is basically a maze of pipes luckily we've been here before!

Suddenly hammer bros ran towards them

Luigi: Hey watch out! Hammer bro attack!

Daisy: I'm going to enjoy this!

Mario: Let's show these guys some of our new moves!

Luigi and Daisy: Let's do it!

Mario Luigi and Daisy found the drill power ups and used them to fight the hammer bros

Daisy: Yes! I love these new power ups!

Mario: I know! Ever since we found the wonder flower these power ups have been everywhere

Billy came out of his hiding spot

Billy: Mario? Luigi? Daisy? Is that you?

All: Billy!

Billy hugged the three of them

Daisy: we're glad your ok but first... you are in so much trouble young man!

Billy: what?!

Daisy: Not only that you teamed up with the koopalings, almost got lost and have we were really worried! If I was your mom I would ground you for a month! But since we're your babysitters your going to do what we say for here on out! Understand?!

Billy: Yes ma'am!

Then Mario and Luigi saw lava heading there way

Luigi: Uh Daisy? You might want to lecture him later!

Daisy: why?

Mario: Because of the lava!

Daisy saw the lava and the four of them ran off

Mario Luigi Daisy and Billy make it out of the cave in time

Billy: Fantastic! you guys are the greatest!

Luigi: Yeah well they don't call us Super for nothing!

Daisy: don't think a complement gets you out of trouble

Billy: Aw man...

Mario: They're going to call us barbequed! It looks like the Koopa Kids super heated the volcano!

They could all see the lava coming out of the volcano

Luigi: Look out it's going to explode!

Mario: Come on! We have to move fast and plug that leaking volcano!

Daisy: this calls for an elephants strength!

Mario Luigi and Daisy broke a few blocks until they each got an elephant power up and became elephants

All: Wowie zowie!

Billy: whoa! That's so cool!

Daisy: if you think that's cool just watch this!

The three of them hit a bolder towards the volcano at the same time

Mario: Boulders away!

The boulder lands on top of the volcano and stops the eruption

Billy: Wowie zowie! That was unbelievable! Way to go!

Mario: For a first time plumber's helper you aren't bad yourself!

Daisy: now we have to get you back home

Luigi looks at his watch

Luigi: Uh oh! Billy folks are gonna be home in 15 minutes!

Mario: Then we'd better get back to that warp zone and get back to Brooklyn!

Daisy: wait! Aren't you guys forgetting something?

Mario and Luigi realized the three of them were still elephants

Mario: Oh right!

They all stopped using the power ups and became humans again

Daisy: Ok now we can go!
