is there an item that stores the musicblocks? Is there any advantage to collecting them all? is the GNG musicblock a similar item to a regular one? Thanks!
1. You can put them in your storage case. No bag for it, if you mean that.
2. Yes, there is a badge and trophy, if you manage to have all musicblocks of the same version in your bag at the same time.
3. Looky here
There is an advantage to collecting them all: If you display a musicblock trophy on your shelf, you can click it and get a menu to play any of the five tunes it represents, thus obviating the need for musicblock storage altogether.
