Instructions
Give Tauros food. Since Tauros is so physically active, his has to eat constantly. Throw a piece of meat at him to get his attention and lull him into a false sense of security.
Throw rocks at Tauros. Even though you are not allowed to use other Pokemon to attack Tauros, you can still pick up rocks and throw them at him. This will both anger and weaken him, making him more vulnerable to capture.
Use your Safari Balls carefully. Do not throw a Safari Ball at Tauros before either feeding or attacking him. The ball will likely miss, since Tauros tends to keep his distance. If you throw the ball and miss, he will run away and you will have to find another specimen.
