Ok so @galactic-knightmare as a au in we’re king boo and Luigi have a father-son relationship and I really needed to practice drawing king boo so what did I decide to do is use this AU as fuel and inspiration
So here’s a bunch of doodles of king boo and some boo’s as well as lovely little Ghost Prince Luigi. full warning though as u can see I don’t necessarily know how to draw baby Luigi and I’m still getting the hang of drawing king boo I did this without reference (because my phone was charging) so it’s not the best of the best but either way I figured I’d still share it because at the very least I think the interactions are cute
These first couple of doodles are old their When the first few chapters were out so these were just to try and find out how exactly they would look. So it’s nothing but a bunch of faces and me trying to figure out how in the hell does baby anatomy work my favorite in this page has to be Luigi trying to climb onto king boo
just more practice in general, you can see that I tried drawing king boo kind of levitating Luigi but I gave up on drawing baby Luigi halfway and then jumped to adult Luigi but with these doodles I had an actual reference of what king boo looks like
Here i start doodling little scenes of what I imagine has happened in the AU so kind of little head cannons I just realize that (I made Luigi a little bit of a problem child when it comes to washing) and you know what I stand by it I don’t think he would like it when he hast to put his bandanna or hat or himself to wash
On the top right Luigi is a little upsetti spaghetti because he’s constantly being changed into a bunch of different outfits because of course the boos need to find out which clothing actually fit him (although king boo is pretty sure that’s just an excuse) you can see that I have a little list and it’s basically just what I imagine Luigis first three words to be I think it’s Canon that the first word he says is papa and boo but I imagine that the third thing/1st phrase he’d ever say is “stop it” (or at least try’s to say it)
you can see just a bunch of different scenarios in we’re king boo would say stop it Because of course I had to give examples
There’s king boo with a flashlight with Luigi on top of him this is from the shenanigans chapter in where one of the ghosts find a flashlight and starts basically flashing everyone even poor Luigi got blinded :(
Then there’s ghosts who are just tossing the painting around of the boo’s that did the whole shenanigans I imagine king boo says stop it but won’t do anything else
And then at the very bottom right you can see Luigi running away after being told that he needs to take a bath
Although my favorite Has to be the drawing to the left of the ghost that you capture in the first Luigi mansion‘s game that was taking a bath helping Luigi out also the little bubble mustache (don’t worry Lu one day)
Top left you can see three ghosts stealing baby clothing from some wire hangers because that’s where I believe they get them 
Just below that there is a painting of king boo and baby Luigi I imagine that king boo wanted to have a serious painting but someone gave Luigi sugar beforehand so he couldn’t stay still so this ended up the outcome although the king doesn’t hate it and probably prefers it this way because he can see Luigi being his silly goofy self
To the right of that is one of the ghosts from the Mario party games holding maracas
And then at the bottom is an entire scene of what I imagine Luigi‘s first birthday to be like. him with shorts and a frilly shirt some ghosts dancing to the left and to the right you can see a pin yada or the poison mushrooms from the games and three ghosts doing the how low can you go game then there’s a floating violin and piano 
And last but certainly not least A Polaroid photo of Luigi eating his birthday cake with icing all over his face I tried doing another little false mustache but clearly failed that’s ok though
Btw you can find the fanfiction of this on ao3 it’s called phantom interference
