- Begin this by getting Blathers onto the island.
- Once he's there, he will be asking for 15 things to display.
- For getting him on the island you will get the recipes for the Vaulting Pole and the Flimsy Shovel.
- These 15 can be Fish, Bugs, and Fossils.
- Make use of the Dodo Airport to travel to different locations to stock up on displays.
- Collect and listen (if you want) to Blathers and what he knows.
- Blathers will get very excited about having enough specimens to open the museum itself and will begin the paperwork.
- That is all you can to this day. Check on him the next day to learn more.
