They made it seem like something really cool but it's just another souvenier, with no function.
Oh well. Anyway, here are the spots. I'm doing this from memory so correct me if it's wrong:
[br][br]
Guitar is at the music store[br]
Necklace, slippers, and sweater at the clothes shop[br]
Football in the toy store[br]
Tie and paintbrush in the classroom[br]
Hat in the (Brazil?) brochure at the travel place[br]
Basket/purse/bag at the food court[br]
Am I missing anything else?
