The powerhouse trio! I would say "pair" for the sake of alliteration, but there are three of the, so it's trio. What really sucks is that I had the wrong memory card in my GC and didn't know it. So I accidentally created a new save file. I put the correct card in and I glanced at the confirmation scene and hit YES...
Only to realize a split-second too late that I had confirmed that I wanted it to SAVE OVER my good file with the new file I'd accidentally started. I lost everthing! That sucked...
