So, now I need to buy those ears while we’re there! I read elsewhere that they also interact on Luigi’s flying tires by lighting up the colors of the italian flag, they glow orange at the cozy cone, they dance with the music in Small World and they stay dark in dark rides. I can’t remember the rest, but they were not just interactive with the world of color show. I think the boys will love it (ok, so mom will too)!
PS If anyone wants those ears and is not making a trip to DL, PM me and we can work something out and I can get a pair for you.
