It doesn't sound like she lost any toys, as they moved a lot of stuff out in the day before the water came up. But it did make it about half a meter into their second floor, which meant stuff they left behind but moved upstairs, still got destroyed.
At least if the water doesn't reach the floor of the second storey, the people can still live in their house as soon as the water recedes, and only have to clean/remove/replace/repair just the first floor. Otherwise it's a bigger cleanup, and longer until they can move back home.
