I have completed the quest Stretching C, option 1 (Tour of your space). I did this by choosing a background on scratch that showed a bedroom and using it, I then took a screenshot of the background and uploaded the screenshot to the sprites section. After, I edited it by erasing everything but the bed, and moved that to fit directly over the bed on the background, I programmed the sprite so that when clicked it would display a somewhat depressing message. I did this with three more objects in the background, the boom-box, the mirror and the floor. The whole room is a reference to the game Undertale which becomes clear when you click the floor. You must have played the game to understand though.
