Earlier, when I was playing Animal Crossing: New Leaf, I took my lava lamp to Cyrus to customize. I asked for a green color and waited 30 minutes, as usual. However, when it was done, the lava lamp came back red.
So I took it back to Cyrus and asked for red to see if it would come back green, and he said that all that would do was restore it to its original state, which was sort of bluish, perhaps maybe some would call it green. Either way, it certainly was not red when I bought it.
