during the first Halloween event i wasted a bunch of donuts

for those that don't know the Halloween had candy as the currency. i was out and had a few drinks and was playing the game while laying in bed before going to sleep and didn't realize what i was doing. There was a something called a spooky box i believe and i think it cost 2 donuts but i don't remember exactly. so anyways for some reason that night i thought it said it cost 2 candies to buy this and not 2 donuts. So i was spending my donuts and was winning candy and was like awesome i spent 2 candy and won 10 candy and some TP and eggs as well. then when i was done i was like why and i 20 donuts lower than i was before and then i realized how stupid i was.

D'OH
