Collect the rare creatures that are attracted to seasonal plants and give them to 
Tortimer! He'll trade you limited-time event items based on how many rare creatures you give him!
If you complete all the tasks Tortimer has for you, you can view an extra-special ending!
STEP 1
Try Gathering Seasonal Seeds!
If you fulfill animal requests during the event, you can sometimes get seasonal seeds from them.
White-Peony Seeds
Purple-Peony Seeds
Note: You can also buy White-Peony Seeds from Lloid in the garden, and you can get Purple-Peony Seeds via Flower Trade.
STEP 2
Try Growing Seasonal Plants!
You can plant the seeds you gather to grow seasonal plants! You can speed up the growth of your plants by using 
Flower Food. You can also use Leaf Tickets to have Lloid fertilize your plants for you!
STEP 3
Try Catching Rare Creatures!
Once your seasonal flowers bloom, they will sometimes attract rare creatures.
- Rare creatures drawn to
White Peonies:
Plum Ripplewing
- Rare creatures drawn to Purple Peonies:
Citrus Ripplewing
Catch a bunch of them, and give them to Tortimer!
Aim for Completion
Hard Tasks
- You can attempt hard tasks once you've completed all the tasks from the first half and second half of the event.
- Hard tasks have a higher difficulty than the other tasks.
- When you complete hard tasks, you will earn recolored versions of the furniture and clothing rewards from the first half and second half of the event.
Note: Hard tasks are available from when all other tasks are complete until the end of the event period, but clearing all of them will not unlock another ending cutscene. Additionally, rewards from the hard tasks will not be displayed in the Catalog.
Pro Tip
Cooperating with Friends Leads to Good Things!
You can share the rare creatures you catch in your friends' gardens. If you do, Tortimer may sometimes give you seeds! Plus, catching the rare creatures that your friends share with you will help you complete tasks!
Cooperating with your friends and sharing a lot are the keys to success!
Note: Creatures you share will disappear from your inventory, but the numbers being tracked in your tasks will not decrease.
Lloid Can Help!
When you want to be sure to catch a rare creature, you can have Lloid catch it! Use 
Leaf Tickets to ask Lloid for help, and he will definitely come through for you!
If you need help, don't forget you can ask Lloid!
Trade Seasonal Plants for Items!
You can trade seasonal plants you harvest for some nice items! You might even get items that can help you during the event, too. For more information, talk to Lloid!
Note: Item exchanges can only be made during the event period.
