The vault is the place where every item you have collected is stored.
Trophies & Stickers
Trophies are prizes you receive during the game that have explanations about the person or object that is in the trophy. Stickers are also rewards for your acomplishments, but you can use these ones as power-ups.
Trophy Gallery
Here you can see your trophy collection.
Trohpy Hoard
In here you are able to arrange your trophies and make funny snaphots that you can save in your album.
Coin Launcher
In the last game, you could use the Lottery to win some trophies, but that really needed any strategy. So now you have the coin launcher, a place where you fire coins to get the trophies you're missing or some stickers.
Sticker Albume
Watch your stickers in a neat and ordered way.
Sticker Center
Arrange your stickers to create snapshots. It is similar to the trophy hoard but with sitckers instead of trophies.
