Easter Egg - UFO Sightings on Mt. Angrio
On Mt. Angrio (AKA Ride the Mountain), you normally can go from the base to other parts of the mountain using helicopters. You can replace the helicopters with UFOs. Enter the purple circles next to one of the helicopter launch spots (the signs #1-6). As soon as you press A to use the helicopter, hold down B and up on the +Control Pad. Once it loads, you will be riding on an alien spaceship wearing glasses.
