While doing some research on the different Splatoon Vendor NPCs for a potential comic project I have in mind, I learned that Crusty Sean is canonically a tiger prawn, specifically a Japanese tiger prawn! Seeing how IRL prawns of his species have these really pretty stripes, I couldn’t help but headcanon that Sean also has some nice looking stripes he keeps hidden under that fried jacket of his haha~
