last week i had a fucking brain blast regarding how its mentioned murch and spyke are both from a region north of inkadia and the splatlands
probably an area with a high urchin population
and i thought to myself it cant really get anymore north of tokyo than hokkaido, right? and apparently hokkaido is known for its urchins, or uni, which are a delicacy
uni from hokkaido are described as buttery and filled with umami which isnt related to murch or spyke but i just wanted to mention it
so i think spyke and murch, as well as other urchins like oonie from ink theory/yoko and the gold bazookas are probably from the splatoon equivalent of hokkaido
this is probably not as revolutionary a thought as i think it is
EDIT: im now even more inclined to believe this because i looked into the etymology of the names of some of the background urchins
kitamura and murasaki are both named after kita murasaki uni, or northern purple sea urchin, kita means north and when you google kita murasaki uni, the top god damn result is the hokkaido uni shop
oonie is also obviously named uni
this rlly feels like a Duh moment. it might be obvious and it might not be i just feel like i dont need to get that deep into it. it just sounds right
