Enter the Town Hall and sit in the mayor’s chair located behind Isabelle’s desk. Isabelle will approach you once you sit down, and speak to you, giving you a variety of dialogue options. Select “Check approval rating” to see how the villagers view you. If it is not yet 100%, there are several things you can do to quickly reach the perfect goal. If it has, you are ready to enact an ordinance.
Changing the town music—Speak to Isabelle in the Town Hall. She will give you the option to change the town music, but only if your town is two in-game days old or more. Changing the town flag—Speak to Isabelle in the Town Hall. Putting something up for sale at Re-Tail—Visiting Re-Tail (the pink arrow icon on the map at the bottom of the screen), and talk to Reese, the pink alpaca. Posting something on the bulletin board—Go to the bulletin board next to the train station (northernmost part of town) and hit A on your console, and then enter your message. Donating a fish, bug, or fossil to the museum—This can be done after capturing a fish with the fishing rod, catching a bug with the net, or digging up a fossil with the shovel. Enter the museum, which is on the far left side of Main Street, and talk to Blathers.
Removing trash from the water by fishing—At times when you fish, rather than pulling up an animal, you will come up with a piece of junk, which can later be disposed of. Note that this is a random occurrence. Introducing yourself to villagers—This can be done by approaching villagers and hitting the A button to converse with them. Sending letters—Buy letter paper at the Nookling Junction. Open it in your inventory, enter a message, and send it by giving it to the duck working at the Post Office (found on the left hand side of Main Street). Pulling weeds—This can be done by standing over weeds, which appear as brownish green sprouts of grass, and hitting the Y button. Watering flowers—This can only be done if you own a watering can, which can be purchased at the Nookling Junction. With the watering can equipped, stand in front of the flowers and hit the A button to water them.
