Practice

Practice is a minigame with a conveyor belt that gives you all plants, even upgrades! It is set to whatever you want at the start. All zombies will come, and there will be new zombies. Dr. Zomboss will not come, no sunflowers will come either. This game is unlocked after you get the Golden Sunflower trophy.
