Your daughter needs to know that Pentax cameras are worthy of more than just farting around with them, and at least she could reset the camera settings back to where they were before she disgraced it so with her farts on it.
Look at your exposure compensation on the camera and dial it down such that the whites aren't clipping. And if you're not sure, set your camera to indicate the clipped highlights on your instant preview (on the Playback submenu). Then you can know for sure you aren't overexposing like that again.
