The Sims 4 Feeding Frenzy Quest Breakdown

- Search and Investigate Plumbird Evidence in Crystal Valley
In each neighbourhood in Gibbi Point there are these large fossils on the ground that have to do with the Peculiar Plumbird. You’ll want to find the one in Crystal Valley and click on it and choose Investigate Plumbird Evidence.

You’ll find this item between the area with the topiary and the electric lagoon. Once you complete your investigation your sim will get an action card with more information as well as a notification.

- Rehome a Butterfly or Moth
Around Gibbi Point you’ll see these really cute flower topiaries and when you click them you have the option to rehome butterflies and moths. You’ll first need to catch or raise one and then you can come back and rehome it so it can live there forever.

- Catch a Delicious Fish
I’m not sure why it specified delicious, you just need to catch a fish. I have satisfied this with jelly fish, a koi fish and more. Click on any fishing spot and go fishing until your sim catches it.
- Deliver Fish to Peculiar Plumbird
After catching the fish you’ll need to find the Plumbird (go to your relationships panel and focus the camera if you can’t find them). When you find the bird you can click them and choose deliver fish to bird.

- Discuss Plumbird Evidence with Gibbi Point Locals
After you’ve investigated the evidence you’ll get this task. You’ll need to find “locals” so sims who live in the area and came with this pack.

You’ll click those sims and choose discuss Plumbird evidence and they’ll give you some information about Plumbirds!

Once you complete the initial three quests for the Peculiar Plumbird you’ll unlock the community spirit quest which will continue to tell you more lore about the weird bird.
