This crustless loaf of bread was baked at a corner-store kind of bakery. It was left inside its bag in a cupboard for two and a half days and turned out as seen. A possible influence factor for the mold spreading so quickly could be that the cupboard is in the tropics, and the "experiment" was performed during the rainy season (meaning the temperatures were low, and the humidity was high).
