In the lair's arcade Raph was playing dance dance revolution and his brothers and Lizzie were watching him

Leo: I don't think he's got this

Mikey: hey leave him alone!

Leo: What? I'm just saying he doesn't have this

Raph: You're just trying to get in my head

Lizzie: I believe in you raph!

Raph: thanks Liz!

Splinter walked in the arcade completely sick. Everyone looked at him causing Raph to lose the game

Splinter: Ow! my brain!

Splinter sneezed

Lizzie: bless you

Mikey omigosh! Splinter's a zombie!

Donnie: Mikey zombies are interested in other people's brains

Lizzie: zombies aren't real splinter just has-

Raph: Rat Flu. This is not a drill. I repeat this is not a drill!

DOWN WITH THE SICKNESS!

___________________________________

The turtles and Lizzie are taking care of a splinter in his room

Lizzie: guys this isn't a big deal. He just needs some rest

Leo: this is serious. you haven't seen rat flu

Splinter: I feel terrible. Do I look terrible? Be honest

They all look at splinter and he looks terrible

Raph: You look great not horribly sick at all

Lizzie: just a few tissues and you'll be fine

___________________________________

Everyone leaves splinter in his room and figure out a plan in the living room

Raph: He's horribly sick

Lizzie: what should we do?

Donnie: Look Lizzie a flu this intense is going to affect all areas of his brain. I'm talking the full seven stages before his body naturally heals itself

Raph: You guys know what the full seven stages mean?

Lizzie: what does it mean?

Raph: it's another chance to get whatever we want!

Lizzie: wait what?

Mikey: But poor Dad. He must feel terrible. But lucky us he'll say yes to whatever we ask for!

Lizzie: why are you happy? Your dad is sick

Leo: when dad is sick he's so sick he doesn't even know what he's saying. Asking for whatever we want is it going to hurt him

Lizzie: I guess...

Donnie: Only if we make it all the way to the end of the flu stage seven and we never get there

Raph: This year's gonna be different. Nobody's getting bit. Nobody's getting infected

Leo: when we do make it to the end which I'm calling the must say yes stage what are we going to ask for?

Raph: this year I was thinking we could ask for...

Leo: he's got nothing. We're dead!

Raph: I got something, all right? Like a uh...

Lizzie: well if we're really doing this maybe I could ask for yarn? I know it sounds dumb but I think it's fun to play with

Leo: Aww!

Donnie: no way! Uranium! we should absolutely ask for uranium if I could finally get my hands on a little of that we would be virtually unstoppable!

Mikey: What about a brick oven for pizza?

Leo: Who's gonna clean that? What we should ask for is matching unicorn onesies. Those are sick! Pun intended and I nailed it

Lizzie: hahaha! You totally did

Raph: I got this. I'm going to ask Splinter for something that benefits all of us

Mikey: This is so exciting! But terrible for Dad...

It's suddenly got really cold in the lair

Raph: Buckle up team. It's about to get weird

Lizzie: how wired?

Raph: really wired

STAGE 1: FEVER!

___________________________________

In the living room the turtles and Lizzie were covered in blankets while the entire lair was freezing

Mikey: I hate stage one. Think warm thoughts. Pizza ovens bricks from Italy and wood chips roasting

Raph: We're four hours in. His fever's has to break soon

Leo was wearing a winter Jacket

Leo: I told you guys to plan ahead. Now I'm sitting here all toasty

Lizzie: it's honestly not that bad for me

They all see splinter walk out of his room only wearing underwear. Then started attacking the turtles and Lizzie so they started running away

STAGE 2: WILD RAT MAN!

Mikey: Don't eat me! Raph's tastier!

Lizzie: I can't believe I'm being chased by a rat!

Raph: Suits on! Suits on! Donnie get the device ready?

The turtles and Lizzie put on hazmat suits. Donnie made Lizzie one while splinter had his fever

Raph: Donnie get the device ready!

Donnie took out a giant hamster ball from his lap

Donnie: oh it's ready.

Raph: nice! Alright let's get him inside!

Leo threw pizza inside the hamster ball and splinter went after it. Then Lizzie closed the ball shut

Donnie: Okay this should hold him for a while

Lizzie: is he going to be ok?

Raph: he's is fine!

Leo: are you sure?

Raph: yes! Splinter loves pizza and confined spaces you can barely breathe in

Mikey: Donnie is it going to hold?

Donnie: most definitely!

Splinter broke out of the hamster ball and escaped into the kitchen

Raph: Mikey follow me and be careful. We can't afford to lose anyone before stage 7

Leo: I thought we all agreed it was now called the must say yes stage

Lizzie: Don't worry I'm still calling it that

Mikey: It would be easier for me to be careful if I knew you were gonna ask for a pizza oven

Raph: I'm still thinking!

Donnie: Quick question is uranium still on the table?

Lizzie: what about yarn?

Raph and Mikey go look for splinter while Leo Donnie and Lizzie take off there hazmat suits

Leo: these things don't breathe

Donnie: I know right?

Lizzie: can you at least put in air hose or something?

Donnie: that's probably a good idea. now are we sure we're safe?

Leo: Calm down. We're fine. Raph and Mikey have it under control

Raph and Mikey run out of the kitchen and are being chased by splinter.

STAGE 3: CAPTAIN CUDDLE CAKES!

Raph: Stage three! Stage three! Stage three!

Donnie Leo and Lizzie immediately put the suits back on and run away with Raph and Mikey

Raph: Why weren't you in your suits?!

Donnie: it was Leo and Lizzie!

Leo: No one forced you to Donnie!

Lizzie: also how is this my fault!? And what's stage three?!

Donnie: long story short dad wants to hug us! if he does we'll get infected!

Then Leo tripped and splinter hugged him

Lizzie: Leo!

Splinter: I love you!

Leo: no! I'm your least favorite!

Donnie: Leo's infected. Quarantine him.

Mikey Raph Donnie and Lizzie trap Leo in his room

Leo: Hey you need me to get to the Must Say Yes stage. We need to ask for the onesies...

Leo fell asleep on his bed

Lizzie: I'm sorry Leo but I'll- I mean we'll take care of you until you feel better

Raph: Down to 4. Alright let's be careful so the rest of us can make sure we get what we want. Who's got eyes on dad?

Suddenly splinter was dressed as a ninja and cut there hazmat suits into a million pieces

STAGE 4: NINJA SUPREME!

Raph: where did he go?!

Then all the lights went out

Lizzie: don't worry guys. I can see in the dark

Mikey touched Lizzie's butt by mistake

Mikey: guys I think I felt him!

Lizzie smacked his hand away

Lizzie: hey! Watch where you put your hands!

Mikey: sorry!

Lizzie looked around and saw splinter go into Donnies lab

Lizzie: Donnie splinter just ran into your lab!

Donnie: oh come on!

Donnie went after splinter but came back with a rat bite

Lizzie: what happened in there?

Donnie: nothing. I'm fine. I just cut myself on that old door. Everything's okay. Raph did you decide what we're going to ask for?

Lizzie: is it yarn?

Raph: I'm going to ask for-

All of a sudden splinter started singing but it was the worst singing ever

STAGE 5: KARAOKE LOVE SONGS!

Mikey: I can't feel my ears! Nothing is worth this!

Lizzie: his singing is terrible!

Raph: We're so close. Only 2 stages left!

Donnie got sick from the rat bite

Donnie: and three totally healthy turtles left. why is it so hot in here?!

Mikey Raph and Lizzie quarantine Donnie in his room

Donnie: your not going to get away where without Donnie! I'm the brains behind this operation!

Mikey: what stage are we on now?

STAGE 6: FANFICTION!

___________________________________

Back in the living room splinter was telling his story to Mikey Raph and Lizzie

Splinter: we open on noodle shop and It's raining. Lou Jitsu hot soups 2 assassins! Then a doorway opens and out walks Jupiter Jim and we smash 2 titles together!

Mikey is writing all this down in a notebook

Mikey: This is amazing. Keep going!

Lizzie: maybe I should write fanfiction

Raph: We're almost at stage seven. This is the closest I've been to success!

Mikey and Lizzie both sneezed so Raph quarantine both of them in separate rooms that were right next to each other

Mikey: We're done. Raph is totally going to blow this. He has no idea what to ask for!

Lizzie: raph said he knows what to ask for and I'm not sick!

Leo: hey Lizzie I love you since the moment I met you! I want to hug you all the time!

Lizzie: that's really sweet dream Leo but I know none of this is real so I'll wait until I wake up...

She passed out on the floor

Raph: raphs got this!

STAGE 7: MUST SAY YES

Raph is standing in front of splinter ready to ask for anything

Raph: dad I know you'll say yes to whatever I ask for and that's-

Leo: hugs! Raph wants hugs!

Splinter: my favorite son!

Splinter hugged Raph and he got sick
