If it gets to in front of an actual judge, they would likely conclude that the average person should have been able to recognize the characteristic image of Mickey Mouse. So they won't even bother with asking whether the prompt actually contained those words or not.
Yeah, I guess that works for characters like Mickey Mouse. But for every Mickey Mouse there are hundreds or thousands of other characters that are less widely known.
Those very likely won't get in front of an actual judge, since the damages would be small enough to make a long court battle pointless, so the question would be moot.
