1. This is an educated guess of yes because Im preeeetty sure I have seen her in my game.
2. Summer season, on the later side of the season. It's kinda muggy so there's a lot of thunder. (I am again guessing)
3. Amiibo Rv visits (like inviting Sable) or redeeming a fortune cookie for a regular 3DS. I dont know which number fortune though.
4. 150! and I loved every single one
5. Pocket Camp hours are super easy to memorise because they go in 3's. I don't know the exact time but having played a good deal of PC so I want to make the educated guesses of: Morning is 6am - 12pm, Afternoon is 12pm-6pm, Evening is just 6pm to 9pm and Night time is 9pm to 6am.
6. If Im not mistaken 1:30AM. Suuuper late sleepers.
7. Have a friend visit your town and buy something in your Nook's shop and a 250,000 bell spending requirement... I think? Another worthwhile detail is it's part of the final upgrade to Nooks.
8. KK Island is a remix of the original island music from the first Japanese language Animal Crossing game and KK song is Totaka's song of course Totaka is referencing Kazumi Totaka.
9. Im going to assume this is in reference to Kazumi Totaka composing all the KK music or that K.K. is also called Totakeke.
10. Visit the reset center a certain number of times but I actually dont remember the specific requirements. I need to brush up!
11. Wild World and you could shoot him down! He mentions it in future games too.. poor guy...
12. Sunny, Meow and Bao, Emerald and Cupcake!
