Something creepy happened with my GamePad today. I was turning on my Wii U GamePad to play Super Mario Maker when it started showing a weird blue circle thing, it's kind of hard to explain what it looked like. The best way I can explain it is it looked like the bottom half of a large blue circle with some white and red dots here and there and with a black background. It appeared for about 5 seconds, then it started up normally. I don't know if it happened on the TV too because I turned on the Wii U before the TV, and the blue circle thing disappeared before the TV turned on. Anyone else have this happen to them? If you need any more information let me know.
EDIT: I did turn it off and nothing weird happened. I'll try turning it on in a little while and see if it happens again.
