Stinky the Snail and Bernie the Bee are also available in this game mode, each one can be bought for $7,000 at Penny's Space-Time Emporium. At midnight, they will require water and bug spray or music again, and the cycle continues. Once they are at full size, the player must water them every day and make them happy after which they will begin dropping coins every 30–60 seconds or so for up to a full calendar day. Once they are obtained, the player must care for them by watering them and meeting their other needs until they are fully grown. The objective of the mode is to acquire plants, either by random drops in any of the other game modes, or by acquiring them from Crazy Dave.
