apparently a hidden achievement. i'm actually not sure

*SPOILER* not much of a spoiler really but still a spoiler technically. there are jackfrosts that can follow you around the city as long as you dont go too far from them the achievement is just finding them i think. idk if there's a follow up or something, but i gathered them all up together just in case there was one. 2nd pic is nothing special, i just wanted to show them stacked up, they seem to "glitch" and teleport around if you bring them to the sealed chests and that let me "stack" them lol
