Kindle Fire is LITTERALY about to be on fire?

My sister just got a brand new kindle fire about three days ago and its worked fantastic, except for nowadays. My child brother came into my space saying “Big iPod hot” (Big iPod means Kindle Fire). I went to go investigate and found it lying on her bed off the charger. When I went to go touch it, I almost burned my hand! I tried to turn it off, but it just stayed on the lock screen. I went to unlock it, but the display is frozen. Any ideas on what the problem may well be and how I could fix it?

So for Christmas I got a kindle fire. Its incredible!!! Unroll last night. I plugged it in to charge but I was also employing it to play video games and read. So there I was. Charging my kindle fire. And taking part in and studying at the exact same time… at some point Ifeel asleep……negative idea…. when I woke up my kindle was LITTLERLY ON FIRE! Jk but it was burning and when I got over to select it up IT BURNT ME! IT FELT LIKE Placing YPUR HAND. Under REALLLY HOT WATER FOR A Extended TIME!!!!! So I picked it up by the charger and place it on my night stand….went back to rest…when I woke up it looked fine untill I picked it up…the back was…sorta sticky and when I slide my fingers acroos the display.(like I do to get dust off) it was sticky and occasionally produced that weird cooler like when u place finger nails on the screen and slide….really should I inform my mothers and fathers what occurs? Since they are the form of parents that get mad above nothing at all…
