• he seems like he'd love potatoes and 4-leaf clovers for being adorable,

• ralsei would 100% make Shepherds Pie, as it's both a play on the fact he's a goat and its pure Irish Cottage-core (that's what chatgpt said :p)

• his color pallette is white, green and pink, which is the old flag of the Newfoundland and Labrador flag (also oldest flag in the world to ever use pink!)... it's also the original Irish flag that inspired the white, orange and green Irish Tricolor flag,

• despite his soft and pacifistic nature, he has a fighting spirit, as he is surprisingly resilient and effective in combat,

• since he is shown to be self-loathing, he's likely drinks a lot of vodka to drown the sorrows - with vodka being made from potatoes and him probably seeing it as a sort of "healing juice",

• there's no way in hell you would never see ralsei celebrating st. patrick's day in some way,

• refers to an elevator as a lift in chapter 1 (seems british, but I see it as more proof for mick ralsei!),

• a fantasy-like wizard figure with somewhat religious undertones (in-universe, not irl) and seems to hate himself enough to think he doesn't even exist... sounds almost like... Irish Catholic guilt!,

• would not surprising to see a meme of IRA Ralsei in a ski mask blowing up a car (and blaming Spamton for putting a bomb there)

to make a stronger case: let's say in later chapters, ralsei gets a orange scarf
orange is the color of Bravery, which given the direction the story is going, he might just get an orange scarf!
it would not only be a satisfying finish for his arch, but would also confirm ralsei is Irish-coded!
currently, i think ralsei doesn't really have an irish accent, it's moreso a slight twang
obviously doesn't go overboard, but the way he pronounces a lot of words would be enough to tell he's probably a mick, y'know?

example: what the dialogue box says:

*Eat your food, Kris!,

what he's pronouncing the words as:

*Ate yer foud, Kriss!

susie doesn't give him shit about it because susie is dumb
