Grass Norwegian Roof

Nobody does details like the Disney's Imagineers. This roof in the Norway World Showcase is easy to miss but it is a traditional grass roof. I wonder if they actually bring goats or sheep out to "mow" the roof or if they send up a cast member during off-hours. I prefer to imagine it's a sheep with a haircut that makes it look like Mickey Mouse.
