can anyone tell me why i’m building a snowman?

i was in the process of doing the treasure hunt (found the book in valor, sent me to frosted heights) and i assumed that the giant snowball that let me interacted with it had something to do with the event. (i know better now, i opened the memory and now i just have to wait till tomorrow) but the giant snowball took fifty of my actual snowballs and now has three slots, one of which is fabric. i tried using a carrot and coal, but it would slot in. any idea what i need to finish it/ who’s quest it is?
