The Pretty Cure Palace is where Pretty Cure take a test to see if they are strong enough to obtain the Heartcatch Mirage in Heartcatch Pretty Cure!. The Heartcatch Mirage resides in the palace. To get to the Pretty Cure Palace, you must go to a door with a heart pattern with a little slot in the middle. You must insert Cure Sunshine's Pretty Cure Seed found in Potpourri's bag in the slot so the door can open. After that, you must put the Pretty Cure Seed in a slot in what looks like a chair. Then you are teleported to the front of a bridge leading to the Pretty Cure Palace.
