Many hours later, in late evening, we found something in one of our bedrooms. Near the bathroom, at the border where carpet meets the wall.
IT WAS A MUSHROOM
A pair of 4-inch tall mushrooms were growing out of our carpet.

Just last morning they weren't there and now, about 15 hours or a little more later, there they are!! We managed to take them out and clorox+lots of other things the area.
I swear, the next time I eat a pizza with all toppings, I will never look at that mushroom the same way again.
