umm the flower thing is called a weed killer it means youve got too many weeds in your town and you can get rid of it by pulling out all of your weeds

(ps ok this is a really cool cheat for animal crossing. it will get lots of weeds but its well worth it!

step 1) earn 100,000 bells

step 2)Then change the date on your ds to the year 2000

step3)Turn On animal crossing, save and turn off

step4) Change the date on your ds to the year 2002

step 5)Go Into animal crossing and collect your mail

At first you will get a letter saying you have got 13,000 bells in interest but before long you will be getting letters saying you have got 99,999 bells

PS THE FIRST TIME YOU DO THIS YOU WILL NEED TO DO STEP THREE BUT AFTER THIS U ONLY NEED TO CHANGE THE DATE ON YOU DS TO TWO YEAR LATER AND COLLECT YOUR MAIL!)
Reply:that flower means your town is bad, u can't ever get rid of it, the only way u could was 2 kill it be4 it was full growen by digging it up, if u get the red thing it means u weren't takin care of your town very well, but yeah your stuck with it now
