Valley
The tsunami swept away one of the cleats your husband just bought and creates an entire valley with it.
けい
たに, たにがわ
None
When the water clears, you and your husband go to the valley to look for the cleat and instead you find a bunch of cake (けい)! Maybe this is the tsunami's way of saying, "Thanks for letting me steal your cleat so I could make this valley shortcut."
