On their way to Mount Silver, Ash and friends find a hot spring and decide to soak in it. However, they end up setting off an alarm and a boy named Nelson comes running. After finding out it was a false alarm, he tells them that he is searching for the Legendary Pokémon Entei. He leaves to go continue searching. Team Rocket in disguise come along and pretend to sell smoothies. They trick Ash and his pokémon to getting into the back of the truck. They then close the doors and drive off.
