Gurumin: A Monstrous Adventure

I'm not 100% sure but if you've been playing and play again on a different difficulty level, I seem to have received a few different pictures.
Here are the ones I know for sure - -1 from Parin's Grandpa, 1 from Disk at the shop, I think either 3 or 4 from some of the monster friends. I I think 1, after working for Fan in the sweet shop, maybe 1 after defeating Tokoron. I forget some of the places.

You also receive 1 from Pamela in Town when you're doing the trading.

I had Parin enter Disk's shop 4-6 times and she suddenly asked him," what's wrong? Is business slow?"
He answered "Yes" and had her put up ads for his shp. (note: She can only put the ads where she looks and has a ! above her head. When she went back to the shop to tell Disk that she was finished, he gave her a pic.
I hope this helps.

Clear the game once than play it again with the same file than go to your room and change clothes when the dog is in the the same room after changing parin will here something go outside on the patio and you will notice cylinders hat ask eveyone in town where he is the go tothe last locked house onthe end and he will give u a picture
