Other than when a special event is going on, running faster in town usually isn't all that useful, or at least not enough to merit eating lots and lots of sugary things. Wouldn't it be nice if we could eat a sugary item outside of town, in PvE areas, and get the speed boost from the item?
It would be a great gold sink, since the only sugary thing you can get outisde of a collector exchange or special event drop is Red Bean Cake, and said bean cake is 400 gold for 5 minutes of use. Plus, it seems like Birthday Cupcakes were partially added to help with Hard Mode, since the monsters in Hard Mode all run 33-50% faster and it's harder to run away from them without a speed boost, and since a free speed boost in PvE isn't game-breaking, how about more items that can help out with our speed in PvE? There is no need to make more items that do that, just let us use all the other sugary items outside of town!
Hope I'm not the only one who would enjoy having more places to use the sugary items

[PS - To anyone who would be mad about the idea of getting to rack up sugar points and finish the title as fast as you can click and be able to get a speed boost out of it anywhere in PvE, while being drunk requires you to click a drink at intervals and takes a week to finish, I also support removing the wait time between clicking drinks to get drunkard points.]
