anyways, just a few minutes ago, I had one of those "really, really close calls" with my diamond version. it all started when I was looking to glitch myself a shaymin. so I performed the tweaking glitch, and did all the steps, up until I couldn't go any farther. I hadn't reached the required amount of steps yet, so I figured I would just restart in the mystery zone, where it last told me to save my game. so I did, and I started the long trek again of 64,300 steps north. after about ten minutes, I figured this is taking too long, and I could do it anytime. so I figured I had my staraptor, who could just fly out of there, and I went about going to perform the deed to fly back to jubilife city. Uh-oh. My character didn't show up on the sinnoh map and the placeholder where you choose what city you want to fly to wasn't there. now I started to freak out. I knew that when I was biking the whole way in the mystery zone, some city names would pop up randomly, but not the city- it would stay dark. so I thought I could run up to the point where one of the random city names would show up and then fly out from there. nope. that didn't work Either, and now I was getting REALLY scared. So I sat there for a few minutes hopelessly thinking of some miraculous way of getting out of the abyss, when I spark of inspiration struck me. Sometimes when you were running, the name "Turnback cave" would pop up, just like the city names. so I went about trying to fly out of there- nothing. I slumped in my chair, tears in my eyes, thinking about how I would have to start all over again. block one. When I remembered I had a few escape ropes in my bag. I always keep 5 escape ropes in my bag, even though I don't use them. I figured maybe someday I would use them to get out of a tight situation. so I looked through the bag, used one scape rope, and..... viola. There I was, safe and sound, back in good old jubilife city. I don't think I'll ever try doing that again.
The moral of this story? I think you already know.
"Always keep an escape rope with you- no matter what. it just may save your life one day =) "
P.S. if you have a story where you got out of a sticky situation, please do tell.
