Instructions
Complete Baoba's first task that he assigns to you, which is to capture a Geodude. Enter the first area of the Safari Zone and walk around in the grass until a Geodude appears.
Throw Safari Balls at the Geodude to capture it. Put the Geodude in the first position of your team. Return to Baoba to complete the task. Leave the Safari Zone.
Wait for three in-game hours. At this time, Baoba calls you, giving you the next task. Return to the Safari Zone entrance.
Walk up to the Safari Zone computer and tap the "Desert" panel. Tap the "Plains" panel to swap the two. Pass through the gate into the park to go to the Desert area automatically.
Walk through the patches of grass in the Desert area until a Sandshrew appears. Capture it with your Safari Balls. When you do, put it in the first team position, and then talk to Baoba to end the task. You are now allowed to place objects in the park.
Press the "A" button anywhere you want to place an object. Select an object from the screen that appears to put the object in that spot.
