short sorry!!
-He wears a wedding ring on both his left and his right hand one for each fiancé
-when karl time travels he takes one of sapnaps fire hoodies and one of quackitys hoodies so he wouldn't forget them
-Karl is afraid to lose quackity and sapnap because in every travel adventure he has anyone that reminds him of them end up dying :(
-Karl's love language is hugs and cuddles
-karl is self conscious about his laugh but quackity and sap constantly tell him how much they adore it-when he's feeling sad quackity and him will sing while quackity plays guitar and sap gives him cuddles
-Karl loves cats, their warm bodies, soft fur, and purring makes him feel safe-He uses jokes as a coping mechanism when he's sad
-karl is afraid of the dark and spiders, sap would often prank him with fake spiders
-he had to ban sap from the kitchen because he almost burnt the house down several times in his horrid attempt to cook
-karl LOVES fairy tales. ever since he was a kid he would read all the time, mostly mystery and fairy tale stories
-karl needs glasses and has a pair, he just chooses not to wear them because he thinks he looks ridiculous
-He prefers either lofi, or pop. not like the newer stuff today more like the 2016-2017 type stuff for example
-quackity, sap, and karl all have matching hoodies (i seen a minecraft screenie of the 3 i just thought this was cute)
-karl, despite being the shortest and seemingly most innocent, is the most protective out of the 3 fiancés
i can't think of anymore lol sorry <33
Hope you liked it!!
