Brittany still goes into the cave, but you go around and use a clipping glitch to get inside. Then you meet up with Brittany and carry Olimar. Problem is, that causes ANOTHER cutscene that warps you to the tower again. Go around again and this time you can carry Olimar out. But I create a path through the oak on the first day so I have time to glitch on the next. It takes SOOOO long!!!
