So I got to the cave in Canada and I was stuck at a glowing rock. I took a look at the walkthrough and apparently at this point in the game I am supposed to have learnt the "nagasaki fart" to break this rock, yet, I didnt....So i thought, no problem, Ill go hunt down randy and it will probably enable a cutscene to learn that fart....well, I found hin at the pta metting hall and hes just on his cell phone saying "the pta will call you again if we need you" or something to that effect.....so my question is, 1. When was I supposed to learn the nagasaki fart? 2. Is it possible to still learn it even though I seemed to have missed the time I was supposed to learn it 3. How could a fart spell that is vital to completing the game be something that can be missed? Help would be mega appreciated guys! Thanks so much, I really want to complete this game but I have no idea what to do now that I am missing a vital spell to break this rock to continue the game.
