Skinny's out and about everyday from 10am, rain or shine. Usually, I stop playing shortly after noon, once I've visited Dr Shrunk at the club. I charge my 3DS in the afternoon, then I play again to visit the island at 5pm. (Are they ever going to sell the silver axe!?) Yeah, Skinny gets a lot of sunshine. I'm wondering if she's going to get even darker or if this is it.
Those of you who are still wondering about how this was possible, watch this video, it explains a few glitches and how you can get your character on the railway track, on the roof of Re-Tail or "fly" off the cliff.
You can also do it the easy way if you have the 'tweeter' item from streetpass.
Blow the tweeter while facing the train tracks behind next to the bulletin board, (where the video first shows) and have a friend walk into you, pushing you towards the tracks. Each time you go a little further until you're free.
Very carefully.
Nah just kidding She was one of my original villagers so I've been chatting with her/sending letters/doing favors for a while. She actually gave me the pic as a reward for a favor.
