I haven't, I'm not even close.
But my friend steve, all he has to do is beat Boss Battles on Intense. He didn't even use any of those hammers.
goowan.
Oh how I hate boss battles. I tried for six hours a long time ago, and then I picked it back up about a month ago and beat it on intense on my third try. I still have beat boss battle with 20 and all characters, get all character trophies, get all stickers, play time stuff. I don't bother any more because there's no reward.
yes i did
boss battles on intense was annoying
