Apparently you usually have to do about 550-600 Candy Tree quests to get a Chocolate Costume, unless you have really good luck...
edit: i don't know where that person got his or her answer but i just got a chocolate costume after completing my 35th quest just now (yes, 35, not 335, not 355, it is 35). it really is based on luck. just like how you need luck to win that "one in a million" game or "guess the weight" of the potato, etc. unknowingly i sold it to someone that had it on their wishlist for 520,000 mp, since i'm poor in the game at the moment and I already completed the "have a chocolate coloured pet" goal a while ago when I traded pets with a friend, BUT apparently there's a "USE a chocolate costume on your pet" goal that i probably won't even reach until next year, so hopefully i'm lucky to get the costume reward again between now and then.
The number of quests are unlimited, there is no end to how many you can do.
It is in the undying woods.
