You look for "addCurrency" and "spendCurrency" using query search, and then find their pointer addresses,
after that you pointer search spendCurrency's pointer and this will returns QWORD values, then copy addCurrency's pointer address, after that you replace the QWORD values with the address you copied earlier like this 1234567890h the h represent its as hex so the it'll change the pointer to point the address we replaced which is addCurrency, now you can buy anything freely if you had atleast 50 of any currency, in this case the cheapest thing on the store for xmas is the first Loot box, which is 10 gingerbread or 10 bells, and if you have 15 of one of those, when you buy it'll give you 10 and youll have 25 instead of 5, this is called function replace, and i found this while i testing stuff back then around 764 ish, and no more these specific search and absurd group search that's always gets patched, this method hasnt been patched for nearly 30+ version and still works, while other like survivor base reset, casino caps hack etc etc is patched. I have a script for this game, and its free for most options and i share it on a discord server. if you interested ofc, just lmk on PM, it's also had premium hack in it if you want more stuff, it sometimes doesnt work in certain devices because i dont have every kind of phone to test with
