sometimes jou get a hammer together with other things
watch out there are only 6 in total they break the glass on some challenges but i would use some on the top(clear boss battles on intense) and bottom(collect all stickers) left hand corners and the bottom right(clear boss battles with all characters) hand corner. another hard to get is the collect all songs(directly above clear boss battles with all characters)
They unlock a challenge without having to do it.
I think you can unlock him as a trophy by clearing Target Smash Level 3 with all characters. Or you can just use one of those hammers.
Your thinking of the wrong game its super smash bros brawl, hammers are hidden in the objectives you have to complete in the vault if you complete an objective with a hammer in it you can keep it then use it to break almost any glass in the vault.
