At the Fluffy Puffy Breadshop in Grillin' Village, there is a glitch that can be performed outside the bakery right before it closes. It requires Musashi to fall asleep on a very specific part of the wooden floorboards leading inside, and if performed correctly, the shop's door as it closes for the night will push him inside. When inside, talking to Jam at the counter will reveal that the bakery is currently having a sale. However, this can be done on any day of the week, making this glitch a possible exploit to buy cheaper goods from the Breadshop.
