Note1: taming Snowflake will also unlock a separate achievement.
Note2: Do not damage any of the gifts or else Katey will not accept them.
Note3: To gift Katey Snowflake you must interact with Snowflake in the security room.

The Funny Painting is only available during the Art Appreciation scoop on Day 3. You have to buy the painting from Randolph for $3,000.

You can only find Snowflake early in the game at the Yucatan. First defeat Ted and then to tame her you need to drop 3 pieces of steak for her to eat.
