Tools
You get a gold fishing rod once you find all of the types of fish, and a golden net after you have found all of the types of insects. Your shovel turns golden if you dig a hole, bury it, and recover it the next day. You get a silver watering can after you purchase at least 50 bags of seed at the general store. Put your standard axe in the fountain and pull it out to get a silver version.
Items
Tortimer is a turtle character who gives you gifts only if you talk to him when the calendar reflects a holiday. You can wait for the day or alter the game's calendar to reflect the desired day. You get a leaf on April 1 and a Sailboat model on Explorer's Day. Go to Tortimer on Harvest Day to get a unit of wheat or Nature Day to get a globe. Visit Tortimer on Labor Day to get a picnic basket.
Collecting Bells
You build a fountain once you donate 400,000 bells to the town. Donate 1,000,000 bells to get a windmill and lighthouse in your town. Expand your home by getting a bigger first floor for 120,000 bells and 248,000 bells. You get a second floor once you collect 368,000 bells, and a basement after you get 598,000 bells. You get a kart after you collect 100,000 bells and a parasol after you get 8,000 bells.
