Stone is 20, Azula is 9 and Indigo is 7 

Hype and Holly were sad when a couple years ago Stone told them that he was going to college and was moving into his own pod along with his girlfriend Starlight and they had missed him 

Indigo: mom when is Stone going to move back 

Azula: he's not moving back are you stupid 😠

Indigo: how dare you call me that 😠

The two start fighting 

Holly: girls please 😣

Hype: 😨 Holly are you okay 

Holly: I don't know this is the 7th headache I've had this week 

Indigo: look at what you did 😠

Azula: you're the one who asked a stupid question 😠

Hype: girls stop fighting and no blaming each other 

Azula: but she started it 

Indigo: no she did 

Hype: I don't care who started it Indigo go sit on the couch and Azula go to your room 

(Azula and Indigo share a bedroom and Hype and Holly kept Stone's old room the way it is incase Stone was staying over)

The girls did exactly that 

Hype: Holly do you think we should go see a doctor 

Holly: I think I'll be fine 😣

Hype: Holly please 

Holly: fine 

At the doctor 

Doctor: so have you been having frequent headaches 

Holly: uh yes that's literally why we came here 

Doctor: any vomiting 

Holly: this morning, the other day and 5 days ago 

Doctor: do you mind if I look into your hair 

Holly: uh sure 

Then the doctor saw a lump growing in Holly's head 

Doctor: congratulations you'll be having a baby soon 

Hype and Holly: what 🤯🤯

Doctor: I'll give you some time to process this *leaves to see a patient who somehow has a giant macaroni on his head* 

Hype: how we agreed that we'll have only two kids together along with raising Stone 

Holly: well regardless of weather we planned on having this baby or not we should raise it along with it's older sisters 

Hype: you're right Holly I'll call Stone over 

That evening 

Stone: what's going on 

Azula and Indigo: Stone 😄😄

Stone: hey girls 

Azula: are you moving back 

Stone: no I came because mom and dad told me that they had something to say 

Indigo: you too 

Hype: I'm glad all three of you came 

Holly: we got some new shirts for you 

Azula: that's it 🤨

The kids looked at their shirts and saw that they had numbers based on their birth order 

Indigo: why do they have numbers on it 

Then Hype and Holly pulled out a baby onesie with the number four on it 

Azula: wait a minute does this mean 

Hype and Holly: we're having baby 😄🎉😄🎉

Stone: congratulations mom and dad 

The family hugs 

6 months later at the hospital 🏥 

The kids were waiting outside 

Indigo: what's taking them so long 

Stone: we had to wait 5 hours for you 

Doctor: ok you three can go see your parents 

Then they saw Hype and Holly 

Azula: mom are you okay 

Holly: yes I'm fine 

They show the kids a glittery pink egg with Holly's hair on it 

Indigo: either the doctor got the wrong baby or it has a different dad 

Stone: why would say that 

Indigo: my friend Yippee's mom always has eggs that come from trolls who aren't her dad and you have a different mom Stone 

Stone: your friend's mom's behavior is kinda concerning and my biological mother is dead to me 

Holly: no the doctors didn't get the wrong baby and your father is the only one I love 

Indigo: but why is it pink when we are all blue

Hype: your uncle Topaz is pink and sometimes babies get stuff from different family member like how your sister has your grandpa and aunt Pearl's hair and you have your hair from your great grandma 

Egg: 🥚 *cracks* 

Azula and Indigo: 😱😱

Hype: whoa already 

Holly: looks like this baby was really excited to meet it's family 

Then the egg hatched revealing a baby boy who was glittery pink with Holly's hair and Hype's eyes 

Baby: 🥱

Hype: hello there little guy 

Stone: what are you going to name him 

Holly: we plan on naming your new baby brother Jasper 

Jasper: ☺️

Later little Jasper stayed at the hospital since he hatched early and three months later they were able to take him home where Azula and Indigo enjoyed having a little brother and Stone made sure to visit his little brother
