I find myself accumulating a LOT of snacks (mostly from gardening). It would be awesome if there would be a way to transmute regular snacks into mega-snacks. Might be a bit complicated to implement with all the different snacks, but it sure would make all those snacks seem more worthwhile!
Maybe accumulate 30 levels worth of snacks for a level 8 and 50 for a level 9 or something?
