Continuing the journey to the next town, Ash and the others notice a bunch of people with digging tolls heading in the same direction. Gary arrives and tells them about Grandpa Canyon, and how ancient pokemon fossils are said to rest there. Team Rocket is also at the canyon, and they plan to use explosives to reveal all the fossils, which will also trap many people down below. After Meowth lights the fuse Ash and Squirtle try to put it out, but they do not make it in time. The explosion causes Ash, Misty, Brock, and Team Rocket to all fall into an underground cave. The cave is home to the ancient pokemon Kabuto, Kabutops, Omanyte, and Omastar. The four quickly attack them, but the real threat is on its way. Soon an Aerodactyl appears, and decides to take Ash for a ride.
