Totally thought of this after watching this video and people who made it were awesome with it!

Also, as I was writing these I realized that it is this talk that made characters how they are as adults.

~With England & Chibi-America~

Just watch the video.

And so, now you know where America learned to come up with his crazy ideas on the spot.

~With France & Chibi-Canada~

Still, watch the video.  France would so scar Canada like that.

And it is because Canada was so scarred by this that he remains quiet and has that look and attitude of innocence, because he is trying to gain it back.

~With Prussia & Chibi-Germany~

Germany:  "Bruder, vhere do babies come from?"

Prussia:  "Kesse, it is simple and awezome, just like zhe awezome me!  Vhat jou do is zhis; go to an awezome bar or club, drink awezome beer vith awezomely hot fraus.  After zhat, jou take her and awezomely do vhat I'd do; invade her vital regions vith mein awezome five meters!"

Germany:  "And zhat is all it takes to make a baby?"

Prussia:  "Nein, not always.  Sometimes, or if zhe frau is awezomely hot and awezomely good in bed, zhen it can take many, many more awezome times... sometimes with things like ropes... and blindfolds... and...*starts drooling over thought*

Germany:  "..."  *walks away to leave Prussia to his fantasies*

And thus is the reason Germany got his fetishes and kinks when it comes to engaging in the act that Prussia described and the reason he goes to books to learn how to do things properly instead of trusting Prussia's opinion/advice.

~With Spain & Chibi-Romano~

Romano:  "Oi, tomato-bastardo, where-a do babies come-a from?"

Spain:  *pokes Romano's cheek*  "Aww is my little Roma beginning to grow up~?"

Romano:  *blushes and puffs cheeks out, swatting Spain's hand away*  "S-shut-a up jerk bastardo!  I-a just want to-a know damn-a it!"

Spain:  "Okay, okay Romano, boss will tell you.  *clears throat*  Okay, so what happens is this; a chico meets a chica, he woos her by-"

Romano:  "Just-a skip ahead tomato-bastardo."

Spain:  "Lo siento.  Now, the two go into a witch's garden and find the biggest tomato they can.  They then take it home, tap 3 times on it, offering churros to it, and viola!  The tomato opens up revealing a brand new baby!"

Romano:  *looks down at partially eaten tomato in hand*  "...  So you-a mean to-a say that I-a could be-a eating a baby right-a now?"

Spain:  *waves hands frantically*  "No, no, no!  I said it had to be from a witch's garden!"

Romano:  *doesn't believe him & turns to walk out of the room*  "Ms Belgium!  Tomato-bastardo told-a me something scary!"

Spain:  "No Romano, don't tell on Boss!"  *runs out after him only to face an angry Belgium*

Belgium:  "What have you been telling him?"

Spain:  *gulps and puts hands up while backing away slowly before taking off running*

Belgium:  *shakes head*  "Okay Romano, let me tell you the truth..."

And thus Romano now knew the truth and was not only angry at Spain for lying, but also a bit traumatized by the experience as a whole, which is why he refuses to eat tomatoes that are not from his or Spain's garden; because he is afraid that he may actually be eating a tomato that was supposed to turn into a baby.

This was what Spain was probably picturing:

~With Austria & Hungary & Chibitalia~

Chibitalia:  "Excuse-a me but I-a have a question."

Austria:  *picks up tea cup*  "Alright, vhat is it?"  *takes sip of tea*

Chibitalia:  "Where-a do babies come-a from?"

Austria:  *spit, splutter*  "Vhat brought zhat on?"

Chibitalia:  "Big-a brother France and-a Prussia were-a telling me how they-a couldn't wait till I-a was bigger to-a tell me about-a babies and-a some other-a stuff."

Austria:  *facepalms and squeezes bridge of his nose*  "Italy, please go call for Ms Hungary and bring her here."

Chibitalia:  "Si!"  *runs off and comes back with Ms Hungary*

Hungary:  "Vhat is wrong Mr Austria?"

Austria:  *shakes head*  "Italy, ask her vhat jou just asked me and tell her vhy jou asked it."

Chibitalia:  "Si!"  *repeats exactly what he asked Mr Austria and why*

Hungary:  "...  Mr Austria, *holds up frying pan and is giving off deadly aura*  please let me go teach those two idiots a lesson."

Austria:  "Go right ahead, jou have my support and blessings.  *Ms Hungary nods and hurries out as Mr Austria turns to Chibitalia*  Italy, do jou vant to hear some music?"

Chibitalia:  "Si, I-a would love to-a listen to-a Mr Austria's music!"

And thus Chibitalia got a private concert, which drowned out the screams and swears of pain and suffering as Ms Hungary taught Prussia and France a very important lesson that the two obviously ignored when they told Canada and Germany about how babies are made.

But at least someone as cute as Chibitalia was not scarred for life and was allowed to keep his innocence longer, which is why he can be oblivious to these sorts of matters because Hungary and Austria still protect him from this stuff.

~With Scotland & Chibi-England~

Scotland:  "Alright lass, have seat and pay attention, because I'm about ta give ya an important chat."

England:  "Alright, what is it?"

Scotland:  "I'm gonna tell ya about how wee babes are made."

England:  "Hell no!  I don't want to know about that bloody business!"  *gets up and tries to run off but is caught by Scotland who sits England on his lap, holding him there*

Scotland:  "Alright, now what happens is ya get a girl, which for a runt like you will be hard, and take her to bed where you [bleep] her by [bleep]ing her senseless.  Now ta do that, ya gotta [bleep] [bleep] [bleep] [bleep]-"

~Many [bleep]s later~

Scotland:  "And that be how babes like ya were made."

England:  "..." *sits there horrified as he vows never to let any child under his care learn this before they are an adult*

And this is why England made up a ridiculous story and told it to Chibi-America years later.  This is also why he thinks he needs to shield and protect any young nation under his care from this stuff, so they are not horrified in the same way as he was.

It is also why England can never really stand being around Scotland without getting mad, because he still holds a grudge against Scotland for telling him about this too early.

~With China & Chibi-Japan~

Japan:  "China-san, when I was out at the market, some women were talking about babies-"

China:  "Aiya!  Japan you are too young to be learning this stuff, aru!"  *flees away from Japan*

Japan:  "..."  *still very interested in finding out about this subject*

And so Japan went and sought out those women in the market and asked them himself, gaining the knowledge that China didn't want him to learn yet.

And to be perfectly honest, he wished he hadn't learned of it yet, thus igniting his want for personal space so that he doesn't have to think about intimacy which he believes might lead to him remembering this.

~With Turkey & Chibi-Greece & Chibi-Egypt~

Turkey:  "Okay squirts, it is time to learn what it means to be men."

Greece:  "... Meaning of being a man...?"

Egypt:  "So what does that mean?"

Turkey:  "It means I'll be teaching you about how babies are made."

Greece:  "... But I already know that stuff..."

Egypt:  "No Greece don't spoil this for me!"

Turkey:  "That's right!  Don't ruin things for him Greece!"

Greece:  *rolls eyes and remains silent*

Turkey:  "Alright, so to make a baby you have to get a hottie and take her to bed where you [bleeeeeeeeeeeeeeeeeeeeeee *does motions with hands and body to show what to do*  eeeeeeeeeeeeeeeeeeeeep]  And that is how you make a baby."

Greece:  "... Sounds about right... but you forgot about [bleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep] and [bleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep]..."

Turkey:  "I did not!  That's what it means when you [bleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep]!"

Greece:  "No... that means [bleeeeeeeeeeeeeeeeeeeeeeeeeeeeep] not [bleeeeeeeeeeeeeeeeeeeeeeeep]..."

Turkey and Greece keep arguing about this stuff and dive into more kinky/dirty stuff, completely forgetting about Egypt who is sitting there mortified.

Egypt:  "..."  *Takes vow of silence and walks away*

And thus is the reason why Egypt is silent and doesn't ask questions, because he believes that he might relive this episode again which started by him asking questions.

This is also part of the reason why Turkey can't stand Greece; because Greece already knew all the stuff Turkey wanted to teach him, so now Turkey can't have another him walking around.

Greece on the other hand really doesn't care about this memory since he already knew about this stuff thanks to his culture, art, and mom's teachings.

~With Chibi-Ukraine & Chibi-Russia & Chibi-Belarus~

Russia:  "Big Sister, I was wondering about how babies are made da."

Ukraine:  *smiles at Russia*  "Oh, is Little Brother growing up?  Da that is nice, but why do you want to know?"

Russia:  "Because Little Sister wants to know and asked me, da."

Ukraine:  "Oh, I see.  *gets up and brings Belarus over*  Well, how you make a baby is by becoming one with another."

Russia:  "Becoming one?"

Ukraine:  "Da, becoming one equals baby, and one way you can become one with another is by marriage."

Belarus:  "Then I want Big Brother and I to marry and become one."

Russia:  *Has an uncomfortable look*  "I do not want to marry Little Sister, but I want others to become one with me."  ^J^

Ukraine:  "Oh I can not wait till I have many cute nieces and nephews."

Russia:  "Da, I want to make Big Sister happy and have big family."  ^J^

And thus sparked Belarus's obsession with marrying/becoming one with her older brother while also sparking Russia's want to become one with others, so he can get lots of love and lots of kids to fill up his big empty home.

My only comment is this; It is Ukraine who doomed us all without knowing it.
