The second rival battle. This is the battle where Gary would usually have a level 9 Pidgey and a level 10/11 (can't remember which) starter. Here, our rival has four evolved pokemon at levels 25-28. I had to grind for hours on end just to get as close as I did and it still came down to me getting VERY lucky. Got through it just using one Full Restore, though, so not bad. Took me several attempts to do this, too. Probably should have just grinded another level or two...
Also, sorry about the sound desync. Not sure if there's anything I can do about that...
