I don't know if you've started on the quests yet but I have some information on the mushrooms. To find the mushrooms, you have to search the pages of bunnyrace. The mushrooms are at the bottom of the pages. There are 11 total mushrooms you have to find AND get their code. I recommend storing their codes in your BunnyRace Memo. Once you have all 11 mushrooms combine their codes. You will notice that you are missing the last piece of the code! From there on you will have to guess what the last piece of the code is. It will be numbers 0-9 or letters A-Z. You submit your response to the postman!
