Inside the warden’s office, Kaiser shows the group a basket of Safari Balls and a fishing rod. Ash is delighted and reaches out eagerly for them, but Kaiser once again pulls his gun out and explains the rules of the Safari Zone: all that is permitted to be used are the Safari Balls and the rods. If they break the rules, his gun, nicknamed Thunderbolt, will burn them. He then points the gun at Ash’s head to demonstrate his point. Misty notices a picture of Kaiser as a young man, in which he is holding a Dratini. As Ash and Misty view the picture, Brock tells them that he has heard rumors of a Dratini living in this Safari Zone. Suddenly, Kaiser leaps forward and snatches the picture from Misty’s hand, insisting that there is no Dratini. Ash argues otherwise, but he is silenced by seeing Kaiser yet again reach for his gun. Kaiser leaves the group and walks outside, taking the picture with him. He stares at the picture and apologizes to Dratini, saying that he will never bother it again.
