i remember the time i put bunch of rocks to make a heartrock but it didnt work bcause i dont put high rarity in it. just a bunch of rocks. in a world.
then the game changed it into a gold box,, i think its called a heart box and i farmed it by putting alot of chands in a numbered world. it was years ago.

how abt now? how did last year go? i might want to get prepared for february!
