 * Version 2: Unlocks at 1,500 Thumbs-Up. Adds the ability to zoom.
 * Version 3: Unlocks at 10,000 Thumbs-Up. Adds additional zoom.
 * Version 4: Unlocks at 100,000 Thumbs-Up. Adds maximum zoom.
 * Version 5: Unlocks at 1,500,000 Thumbs-Up. Adds the ability to call Pokémon over to the player. A stamp is added to the player's Passport.
