1) Snowflake - Location: Yucatan Casino - (Keep some steaks handy, just incase.) This is the tiger that is with Tim the Psycho. First head to the Food Court and go inside the Wild West Grille House to get the 3 steaks in the back kitchen. Then kill Tim in the Yucatan. He's very very weak. Now drop the steaks on the ground (there are 3 more on the fake stone mountain inside the Yucatan). And just dodge Snowflake until she eats at least 3. If she gets hurt, it will take more steaks. You will get the The Skill To Survive achievement upon taming Snowflake. Then lead her back to the Safe house and then examine her next to Katey for number 1.
