Ipad not working

not sure what version of iPad the is, but I do know that it is an iPad mini. A couple of days ago my 2-year-old brother got frustrated and decided our iPad would be a good thing to throw. We opened it up and everything was fine. So we used it as normal. Then tonight, my little sister came in and said she was listening to a video episode of her favorite podcast, although I suspect she was doing more watching than listening. So she brings it to me, and shows me the screen--It's completely blank, in that color that you get when you're shutting down any apple device. Only this time, it's not shutting down. It's just sitting there doing nothing. I looked at it, and in a blue box the dimensions of the screen rotated to the right about 45 degrees, and then disappeared and the screen stayed in that color. I shut it down and restarted it, and everything looked normal, so I went back to safari to open the website that the podcast was, and it opened up to "mouse.com"--Whatever that is. And the odd thing about it is that is somehow opened the website with no wifi, and that ipad has no cellular capabilities. i tried clicking a couple things and nothing happened, so I rebooted the app, and the same thing happened. I rebooted it again, and "mouse.com" was gone, and the tabs that were open before reappeared--however, we couldn't do anything, like before. So I tried opening a few apps, and we got the same result-we couldn't do anything, although "mouse.com" didn't open up, sine these were not browsers. The Home Screen functioned normally, as did the buttons, although nothing else worked. The buttons worked like they should throughout all the apps. Any idea what could cause this?

Thanks,
