Fortunatley it was exactly these rodents, strenghtened from the cheese, who would later found the saftey squad! Always ready to eat slippery food floor before anything bad could happen.
Fortunately, none of the food in the city contained potassium benzoate, so it wasn't as dangerous! The heroic rats who accidentally ate a rock that looked like thrown away candy were also hailed as heroes!
Unfortunately the softness was nothing but a completely false ruse, ending up in attorneys and lawyers falling hard on their butt cheeks. For everyone's amusement.
