||Trophy Garden/Swarms/Pal Park||

Learn how to find Pokémon in the Trophy Garden, daily swarms, and Pal Park transfers after obtaining the National Pokédex in Pokémon Platinum.

Trophy Garden:

1. After obtaining the National Pokédex, the Trophy Garden expands.
2. Talk to the owner of the mansion in the right wing to get up to two Pokémon to appear.
3. You can manipulate which Pokémon appears by saving before you talk to the owner.
4. There is no time limit on the Pokémon; the earliest one will not change as long as you do not talk to the owner.

Swarms:

1. After obtaining the National Pokédex, swarms will start to happen in certain routes in Sinnoh.
2. You can find out about swarms by talking to Dawn's sister in Sandgem Town (quickest way) or by looking at the TV (may have to sit through other content).
3. Swarms change every day at 12:00 AM.
4. Saving and reloading does not change the Pokémon that appears; it is always fixed for the day.

Pal Park:

1. Also after obtaining the National Pokédex, the Pal Park will open on Route 226.
2. You are allowed to transfer Pokémon from your Game Boy Advance games every 24 hours.
3. You must wait a full 24 hours to transfer from a specific GBA version again (e.g., if you transfer at 7:25 PM, you must wait until 7:25 PM to transfer from that version again).
4. If you alter the Nintendo DS system's clock, it will restart the 24-hour timer to whenever you changed the clock.
