Souvenir Room
In Pietro's room, there's a secret room there that all of the souvenirs you bought from different places were kept.
To get in to the said room, there's a gap between the closet and the cabinet that has a picture frame. Go straight in and Viola!(Then the title's movie's song is playing. Which is sweet.)
There, you'll see firsthand, the portrait of Sania, Pietro's mom. There's a doorway on the right side. Go in and it'll state that 'Pietro has entered a souvenir shop.'
Unfortunately, I didn't buy all of the souvenirs and still curious about what will happen if I were to collect them all.
I hope it helps. :D
