Well the title isn't entirely accurate, but close enough to the issue I'm having. XD

My Pet Honeypie

Basically I have a repeating background that you can see here, but I want to add a colored box behind my pet and the information so that you can see the text easily as well as preventing the colors from being too overwhelming. But I'm not sure how to do that besides painstakingly creating a background the perfect size of the screen with said colored box at the right spot. Is there a way I could JUST add a box behind all of the other stuff?
