You liar, you didn't make those. You realize that's called plagiarism, right? Regardless of if the Spriter's-Resource says that you don't need to give them credit, you shouldn't steal credit for what they did. I
knew you didn't make those. But now I have proof:
Go
here and scroll to 'backgrounds'. You'll see the Wigglytuff's Guild picture if you click on 'Outside/1st floor of Guild'. He simply copied it, pasted it to MS Paint or another image editor, and cropped it then called it his.
As for the Ice Sea, I can't find exactly where he stole it, but I know he did and I found the perfect picture to prove it:
I found that on Bulbapedia. And the artwork matches 'his' background to a tee.
You almost got away with it, too~ You sly dog. Perhaps if you said you 'cropped them from the game', it wouldn't be against the rules~ But you didn't. So it is.
