Get a golden watering can and have a perfect town!
Basicly, your town's lawn must be perfect. There can be NOTHING on the ground, including weeds, clovers, items, fruit, designs, dead flowers (that includes dandilion puffs), or shells. You also must have nothing buried underground, and have as many live flowers as you can (rare and black (not dead, black) flowers (such as the jacob's ladder or 4 leaf clover) will really help, too). Be warned: it is extremly hard and not for the lazy, time-jumpy, or faint of heart. It takes a long and gruelling expirience to get your town "perfect". You can check your town's status by selecting 'The Environment!' at town hall. If, by some strange, time-paradox, you can actually get it perfect and keep it that way for an entire week, talk to Pelly (or, ugh, Phyllis...) She will present you with (da-da-da!) The Golden Watering Can!!! Yay!
Hope it helps,
