Potted: Complete any level except the roof with plants planted on Flower Pots (Spikeweeds and Spikerocks are not included since they can't be planted on Flower Pots, Grave Buster is definitely not used because it is not planted on Flower Pots). As for aquatic plants, only plants that can be placed on Lily Pads (no Sea-shroom, Cattail, or Tangle Kelp).

Keep off the Grass: Complete any Pool level (Day or Night) with plants on Water only.
