Okay everyone so I came up with an idea for a mini-game called Select 'n' Protect. You have to pick a plant to be endangered and usually it goes this way: the more fragile the plant, the bigger the reward (more gold).
If anyone wants to help me come up with reward sizes, here is the list:
Very small: Tall-nut, Infi-nut
Medium: Sweet Potato, Winter Melon, Homing Thistle
Big: Peashooter, Sunflower
Very big: Potato Mine, Squash, Chili Bean, Hypno-shroom, Sun Bean
Extremely big: Puff-shroom, Guacodile, Ghost Pepper
No using instant-use plants!
