I have animal crossing wild world I saw crazy redd's tent but he won't let me in. I went on youtube but they don't have the answer.How do you get into crazy redd's tent when he says neighbor raccoon?
If you speak to every person in your town, one of them is a member and will give you the code to give to Crazy Redd.





Hope this helps!
